Electric field-induced quasi-elastic inter-landau level scattering in the space-charge-limited magnetoconductivity of n +n −n + InP structures

Magnetophonon resonance and quasi-elastic inter-Landau level scattering (QUILLS) are investigated in the transverse magnetoconductivity, σ xx, of short (1 μm) n +n −n + InP structures under conditions of space-charge-limited conduction. The damping of the magnetophonon resonance amplitudes at large...

Description
Summary:Magnetophonon resonance and quasi-elastic inter-Landau level scattering (QUILLS) are investigated in the transverse magnetoconductivity, σ xx, of short (1 μm) n +n −n + InP structures under conditions of space-charge-limited conduction. The damping of the magnetophonon resonance amplitudes at large E is also investigated. The electric field dependence of the QUILLS process in InP is in excellent agreement with a model that we have previously proposed to describe the process in n +nn + GaAs layers. The observed form of the space-charge-limited current-voltage characteristics (I ∝ V 2) is discussed in terms of the behaviour of electrons in short, lightly doped semiconductor layers under the influence of large, mutually perpendicular electric and magnetic fields.
