Abstract:
With the development of cryogenic applications, such as high-performance
computing and quantum computing, cryogenic semiconductor electronics has become
one of the vital research topics in the IEEE Electron Device Society. Power
consumption of MOSFETs leading to undesired heat is one the major challenges of
CMOS working at low temperatures for these novel applications. In this presentation, I
will briefly introduce the role of CMOS in these applications, review the fundamental
device physics of MOSFETs at cryogenic temperatures and show our recent results.
And these results can be found in IEEE Electron Device Letters:

Tunneling at Cryogenic Temperatures”, IEEE Electron Device Lett., 41, 1296, 2020.

Stacks for Cryogenic Applications”, IEEE Electron Device Lett., 43, 674, 2022.

Cryogenic MOSFETs”, IEEE Electron Device Lett., submitted.
