Abstract

Temperature-and field-dependent electron and hole mobilities were simultaneously derived from admittance measurements on an InP/InGaAsP/InAs/InP long wavelength laser structure. Each carrier's mobility was separated in the frequency domain due to the corresponding different relaxation times from {C} versus log {f} curves. Derived electron and hole mobilities followed the Poole-Frenkel-Type field dependence, indicating the transport of carriers through hopping. Extracted thermal energy gap ( {\Delta } ) and disorder temperature ( {T{0}} ) values were in mutual agreement with previous current density-voltage measurements and from the energy band diagram of the present structure, constructed from other studies in the literature by photoluminescence and photoluminescence excitation experiments.
