Champ Magnétique

The intrinsic photoconductivity of several samples of the alloy GaAsxSb1−x has been studied at 4.2 K in the presence of magnetic fields of up to 65 kG. Values for the band-gap, the reduced effective mass of the carriers, the energy of the longitudinal optical phonons across the alloy composition are deduced from the measurements.

Magnetophonon Resonance

We have carried out experiments of magnetophonon resonance on n-InSb doped at 4.6 × 1013 cm−3 at a temperature of 135 K. The second derivative of longitudinal and transverse magnetoresistance exhibits obviously spin-resolved peaks of magnetophonon resonances involving one or two longitudinal optical phonons. Among these "over-structures" appear spin-flip resonances, particularly the 0−0+ resonance.The structures of the magnetoresistance are explained from the calculation of resonance fields, based on our method of determination of the Landau levels.
