Abstract
The electron cyclotron effective mass in CdTe was measured with photons having energy ranging from 12 to 250 cm 1. The expected dramatic decrease of the mass when the photons energy exceeds that of the LO phonons is shown for the first time. Accurate measurements at 4K were made possible by a free carrier persistent effect occuring in the samples investigated. The magnetic field resonance values at various photons excitation energies were fitted by using a recent accurate calculation of the magnetooptic absorption by Peeters and Devreese. This new theory produces a good fit with the data when taking the electron Frolich constant value ∝ = 0.3 and adjusting the band mass to the value mb = 0.092 m0. Previous results and theory favours the values ∝ = 0.4 and mb = 0.089mo.
