Ge/SiGe quantum electronic devices

Thursday February 28, 2019
3:30 pm

 Presenter:  Tzu-Ming Lu, Sandia National Labs
 Series:  CQuIC Seminars
 Abstract:  One of the building blocks of today's digital technology is two-dimensional electrons in metal-oxide-semiconductor field-effect transistors. These low-dimensional electrons/holes may play an equally essential role in future computing paradigms. Ge/SiGe heterostructures hosting low-dimensional holes have recently emerged as an important material platform for future quantum electronics and spintronics. In this talk, I will first review the fabrication and device operation of high-mobility Ge/SiGe heterostructure field-effect transistors and then present the characterization of the quantum properties of these two-dimensional hole systems. Paths toward quantum computing, including topological and spin-based approaches based on this material system, will be discussed
