WebIn early studies, the Hall mobility of annealed LT-GaAs was shown to be large (1000 cm 2 /V s), while the mobility estimated from photocurrent measurements were nearly an order of magnitude lower (120–150 cm 2 /V s) (Gupta et al., 1991).Using ultrafast optoelectronic measurements at 800-nm wavelength, the electron and hole mobilities in Be-doped LT … In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pulled by an electric field. There is an analogous quantity for holes, called hole mobility. The term carrier mobility refers in general to both electron and hole mobility. Electron and hole mobility are special cases of electrical mobility of charged particles in a fluid under an applied electric field.
