Dr. Gang Qiu is a postdoctoral researcher at the University of California Los Angeles. He received his Ph.D. degree in Electrical and Computer Engineering from Purdue University in 2019. His research focuses on investigating novel low-dimensional materials for advanced electronics and quantum applications. He is currently interested in employing quantum materials for nanoelectronics that are optimized to operate at cryogenic temperature to interface quantum technologies with the classical world.
Abstract
Since the debut of Moore’s Law, this prophecy has governed the cadence of electronic device miniaturization for over half a century. With the state-of-the-art transistor dimension approaching the quantum limit, hopes have been cast on innovative 2D and even 1D van der Waals materials for next-generation electronics.
In this talk, I will present the material growth, device application and quantum transport of emerging 2D semiconductor tellurene. High-quality 2D tellurene thin films are synthesized with hydrothermal growth technique, leading to potential electronic, optoelectronic, and thermoelectric devices. The Quantum Hall effect was observed in tellurene at cryogenic temperatures, leading to the first experimental evidence of Kramers-Weyl fermions in a semiconductor system. Future cryogenic devices that bridge classical electronics and quantum computers based on 2D electronic materials will also be discussed towards the end.
