As technology advances, the demand for smaller, more powerful computer chips continues to grow. Silicon chips, which have been the backbone of technology for over half a century, are reaching their limits in terms of feature size and performance. The tiniest features on today’s chips are approximately 3 nanometers—a fraction of the width of a human hair, which is about 80,000 nanometers wide. To meet the growing need for enhanced memory and processing power, researchers are exploring new materials and processes. One promising avenue is the development of TMD-based semiconductors which could pave the way for the next generation of computer chips.

The Promise of TMD-Based Semiconductors: Researchers at the U.S. Department of Energy‘s Princeton Plasma Physics Laboratory (PPPL) are at the forefront of this innovation. They are leveraging their expertise in physics, chemistry, and computer modeling to develop new processes and materials that could lead to smaller, more efficient chips. TMD-based semiconductors are a key focus of their research. These materials, known as transition-metal dichalcogenides (TMDs), offer unique properties that could revolutionize chip manufacturing.

What Are TMDs? TMDs are ultra-thin materials composed of a transition metal layer sandwiched between two layers of a chalcogen element—such as oxygen, sulfur, selenium, or tellurium. Despite their three-dimensional nature, these materials are often referred to as two-dimensional because they can be as thin as three atoms. The atomic structure of TMDs forms a crystal lattice, which ideally should be consistent throughout. However, in reality, small alterations or defects often occur within this lattice.

Understanding Defects in TMD-Based Semiconductors: Defects in TMD-based semiconductors can significantly impact their electrical properties. These defects include missing atoms or atoms in unexpected locations within the crystal lattice. While some defects can improve the material’s electrical conductivity, others may hinder its performance. Therefore, understanding these defects and their effects is crucial for refining the manufacturing processes of future chips.

The Role of Defects in TMDs: One of the most common defects in TMDs is the chalcogen vacancy, where an atom of oxygen, sulfur, selenium, or tellurium is missing from the lattice. Researchers have found that these vacancies can affect the material’s electrical charge. For example, certain defect configurations involving hydrogen atoms can introduce excess electrons into the material, creating a negatively charged semiconductor known as an n-type semiconductor. This discovery is significant because computer chips rely on combinations of n-type and p-type (positively charged) semiconductors to function.

Implications for Chip Manufacturing: The findings from PPPL researchers lay the groundwork for developing plasma-based manufacturing systems that can create TMD-based semiconductors with precise specifications. By understanding the energy required to form different defects and their impact on the material, scientists can tailor the manufacturing process to incorporate or eliminate these defects as needed. This research also sheds light on past experiments with TMDs and provides a roadmap for future investigations into these promising materials.

The Future of TMD-Based Semiconductors: The potential of TMD-based semiconductors is vast. As researchers continue to explore and understand the properties of these materials, they move closer to creating the next generation of computer chips. These advancements could lead to smaller, more powerful devices that meet the ever-growing demands of the digital age.

Conclusion: The future of technology hinges on the development of new materials and processes that push the boundaries of what is possible. TMD-based semiconductors represent a significant step forward in this quest. By detecting and understanding the defects within these materials, researchers are paving the way for the next generation of computer chips that will power tomorrow’s technology.

NASA’s Roman Space Telescope is set to transform our understanding of the universe, offering unprecedented insights into galactic fossils and the elusive dark matter that dominates cosmic mass. Slated for launch in 2027, this cutting-edge telescope will explore the Milky Way and nearby galaxies, unveiling the secrets of their origins and evolution. By focusing on ancient stellar remnants and the mysterious dark matter, NASA’s Roman Space Telescope will push the boundaries of astronomical research.

Investigating Galactic Fossils with NASA’s Roman Space Telescope

One of the key missions of NASA’s Roman Space Telescope is to study galactic fossils—ancient groups of stars that hold vital clues about the formation and evolution of galaxies. These stellar remnants, including tidal tails, stellar streams, and halo stars, extend far beyond the visible portions of galaxies. The Roman Telescope’s high-resolution imaging capabilities will enable scientists to reconstruct the events that shaped galaxies over billions of years, providing a detailed record of their history.

Robyn Sanderson, the deputy principal investigator of the Roman Infrared Nearby Galaxies Survey (RINGS) at the University of Pennsylvania, compared the study of these galactic fossils to an archaeological excavation. “It’s like piecing together bones in an excavation to rebuild an ancient creature,” Sanderson explained. The Roman Telescope’s ability to observe vast areas of the sky with high angular resolution will allow researchers to piece together these cosmic clues, offering a clearer understanding of how galaxies like the Milky Way have evolved.

Understanding our own galaxy’s history is particularly challenging due to our position within it. Professor Raja GuhaThakurta from UC Santa Cruz emphasized this limitation, noting, “We simply don’t have a selfie stick long enough to take those kinds of photos.” However, NASA’s Roman Space Telescope will overcome this challenge by allowing scientists to study other galaxies that resemble the Milky Way. By comparing these external galaxies to our own, researchers can infer the processes that have shaped the Milky Way, offering a broader context for our place in the cosmos.

Shedding Light on Dark Matter

NASA’s Roman Space Telescope will also play a crucial role in the investigation of dark matter, a substance that makes up about 80% of the universe’s mass yet remains largely undetectable by conventional observational methods. Dark matter is believed to be responsible for the gravitational forces that hold galaxies together, but it does not emit, absorb, or reflect light, making it invisible to traditional telescopes.

The RINGS survey, a potential project for the Roman mission, will focus on studying the halos of galaxies—regions dominated by dark matter. These halos extend far beyond the visible boundaries of galaxies and are often 15 to 20 times larger than the galaxies themselves. By observing the distribution of stars and other matter within these halos, NASA’s Roman Space Telescope will provide critical data for testing dark matter theories and understanding its role in galaxy formation.

Ultra-faint dwarf galaxies, in particular, are valuable for studying dark matter because they contain very few stars and are almost entirely composed of dark matter. GuhaThakurta explained, “Ultra-faint dwarf galaxies are so dark matter-dominated that they have very little normal matter for star formation. Even when they do form stars, the process often blows away more of the gas needed to create the next generation of stars, making them deeply inefficient at producing stars.” These galaxies act as nearly pure dark matter laboratories, offering a unique opportunity to study this elusive substance.

NASA’s Roman Space Telescope will capture high-resolution images of these faint galaxies and their surrounding halos, enabling scientists to observe the effects of dark matter on a much larger scale than currently possible. As Ben Williams, principal investigator of RINGS at the University of Washington, noted, “With Roman, we’ll suddenly have 100 or more of these fully resolved galaxies,” significantly expanding the dataset available for dark matter research.

A New Era of Galactic Exploration

NASA’s Nancy Grace Roman Space Telescope represents a significant leap forward in our ability to explore and understand the universe. Often referred to as the “mother” of the Hubble Space Telescope due to its advanced capabilities, the Roman Telescope is expected to revolutionize our understanding of both visible and invisible components of galaxies. Its large field of view and high resolution will allow astronomers to study not only individual stars and stellar populations but also the broader structures that govern the evolution of galaxies.

By combining the Roman Telescope’s imaging data with deep, wide-field spectra from ground-based telescopes like the Keck II 10-meter telescope and the DEIMOS spectrograph, scientists will be able to apply advanced techniques, such as co-added surface brightness fluctuations (SBF) spectroscopy. This method, developed with contributions from GuhaThakurta, promises to enhance our understanding of the formation and evolution of galaxies, ranging from those comparable in size and luminosity to the Milky Way to much smaller or larger systems.

As we anticipate the launch of NASA’s Roman Space Telescope, the future of galactic exploration and our comprehension of the cosmos look brighter than ever.
