At room temperature, the charge density comes largely from intentional dopants and either electrons (from donors) or holes (from acceptors) will dominate.

Therefore, GaAs is more suitable to be used in applications that are exposed to different temperatures. AA Ali - ‎ Cited by - ‎ Related articles On the temperature dependence of the hall effect and.
