Search for Anisotropic Electrical Properties in Amorphous Germanium

Abstract
Low-field and high-field resistivity in amorphous Ge were measured in both the planer and transverse directions on the same samples, whose thickness ranged from 0.4 to 4 μm. No anisotropy was found, suggesting that the voids recently described by Galeener may not play a significant role in these transport processes.
