Velocity field characteristics of minority carriers (electrons) in p-In0.53Ga0.47As

Abstract

Steady‐state velocity field characteristics for photoexcited minority electrons in p‐In_0.53Ga_0.47As are reported. A low‐field drift mobility of 6000 cm²/V s for ∼10¹⁷ cm⁻³ impurities and a high‐field drift velocity of 2.6×10⁷ cm/s at 7.5 kv/cm are found. There is no evidence of transferred electron effects, a result which we attribute to energy scattering by holes and which leads to an enhancement of electron drift velocity.
