Physicists Find Misaligned Carbon Sheets Yield Unparalleled Properties

A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing — and potentially exploitable — conductive properties.

Dr. Fan Zhang, assistant professor of physics in the School of Natural Sciences and Mathematics at The University of Texas at Dallas, and physics doctoral student Qiyue Wang published an article in June with Dr. Fengnian Xia’s group at Yale University in Nature Photonics that describes how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.

Creation of Weak Materials Offers Strong Possibilities for Electronics

New fundamental research by UT Dallas physicists may accelerate the drive toward more advanced electronics and more powerful computers. 
The scientists are investigating materials called topological insulators, whose surface electrical properties are essentially the opposite of the properties inside. 

“These materials are made of the same thing throughout, from the interior to the exterior,” said Dr. Fan Zhang, assistant professor of physics at UT Dallas. “But, the interior does not conduct electrons — it’s an insulator — while the electrons on the surface are free to move around. The surface is therefore a conductor, like a metal, but it is in fact more robust than a metal.” 

Physicists Decipher Electronic Properties of Materials in Work That May Change Transistors

UT Dallas physicists have published new findings examining the electrical properties of materials that could be harnessed for next-generation transistors and electronics.
Dr. Fan Zhang, assistant professor of physics, and senior physics student Armin Khamoshi recently published their research on transition metal dichalcogenides, or TMDs, in the journal Nature Communications. Zhang is a co-corresponding author, and Khamoshi is a co-lead author of the paper, which also includes collaborating scientists at Hong Kong University of Science and Technology.
