| Abstract: | Measurement of the magneto-Stark effect and of electronic transport properties on GaSe show that, although it is a layer structure, this semiconductor has nearly isotropic electronic states at the forbidden gap. In fact, the valence band anisotropy is anomalous: the effective mass normal to the layers is smaller than that in the plane of the layers. |
