Measurements of the effective g-factor in dilute GaAs 2D electrons

Research output: Contribution to journal › Conference article › peer-review

Abstract

Direct measurements of the effective g-factor in dilute GaAs two-dimensional electrons was reported. Experiments consisted of measuring the Zeeman splitting created by an external magnetic field applied nearly parallel to the two-dimensional electron system (2DES). The spin polarization and the functional form of the in-plane magnetoresistance were shown to be related. A decrease of g* with increasing Bohr radius was inconsistent with the available calculations.
