NettetThere are two schools of thought regarding the impact ionization in GaAs. The first one states that impact ionization rates α i and β i for electrons and holes in GaAs are … NettetElectron Hole Mobility An electron-hole is a term used to describe a missing electron at a location where it could theoretically exist inside an atom. It is able to create an electric current within a semiconductor. Compared to GaAs, silicon has a significantly higher electron-hole mobility.
Nettet19. jul. 2024 · When deposited with lower work function metal of Al, the peak hole mobility of GaSb NWFET can be enhanced to as high as ≈3372 cm 2 V −1 s −1, showing three times than the un-deposited one. The as-studied metal-semiconductor junction is also efficient for the hole mobility enhancement of other p-channel devices, such as GaAs … Nettet10. apr. 2024 · In this study, we examined the (001) surface of two unstrained SiGe bulk single crystals with different compositions [Si x Ge (1−x) with x = 0.14 and 0.60] by high-resolution core-level photoemission measurements and ARPES. The thermally cleaned (001) surface of the SiGe crystal exhibited double domain (2 × 1) reconstruction, where …
