Two-phonon scattering in non-polar semiconductors: a first-principles study of warm electron transport in Si
Benjamin Hatanpää, Alexander Y. Choi, Peishi S. Cheng +1
The ab-initio theory of charge transport in semiconductors typically employs the lowest-order perturbation theory in which electrons interact with one phonon (1ph). This theory is…
Self-heating of cryogenic high-electron-mobility transistor amplifiers and the limits of microwave noise performance
Anthony J. Ardizzi, Alexander Y. Choi, Bekari Gabritchidze +4
The fundamental limits of the microwave noise performance of high electron mobility transistors (HEMTs) are of scientific and practical interest for applications in radio astronomy…
High-field transport and hot electron noise in GaAs from first principles: role of two-phonon scattering
Peishi S. Cheng, Jiace Sun, Shi-Ning Sun +2
High-field charge transport in semiconductors is of fundamental interest and practical importance. While the \textit{ab initio} treatment of low-field transport is well-developed,…
