High-mobility semiconductors refer to semiconductors having electron or hole mobilities greater than doped silicon.
Electron and hole mobilities
The electron/hole mobility characterizes how quickly an electron/hole can move through a semiconductor, when pulled by an electric field. They are almost always specified in units of cm2/(V·s).
