Abstract

Measurements are reported of frequency- and temperature-dependent cyclotron resonance in the ternary alloy Ga_xIn_1- As. close to its lattice match with InP. The bandedge effective mass is found to be 0.041 m_o for x = 0.47. in agreement with earlier measurements. but it is found that the non-parabolicity of the conduction band is approximately double that expected on the basis of k - p perturbation theory. This is thought to be due to alloy disorder. Magnetophonon resonance was also observed. giving a further measurement of the effective mass, together with the first observation of two-phonon-mode behaviour in this material.
