Abstract
Optically detected magnetic resonance measurements of the effective g- value (g) of electrons in type-I GaxIn1-xAs/InP quantum wells are pre sented. The observation of spin resonance on the circularily polarized luminescence is explained in terms of recombination in a one-side p-m odulation doped quantum well and spin thermalization. Quantum confinem ent changes the electron effective g-value. It further induces a stron gly anisotropic g-tensor. A calculation for the g(parallel to)-compon ent agrees well with the experimental data, but the anisotropy can be explained only qualitatively.
