Femtosecond intersubband dynamics of electrons in AlGaN/GaN high-electron-mobility transistors

Not Accessible

Your library or personal account may give you access

Abstract

Ultrafast electron dynamics in the inversion layer of an AlGaN/GaN transistor is studied in pump-probe experiments with 50-fs midinfrared pulses. e1–e2 intersubband scattering and thermalization occur within 200 fs.
