Abstract

The conductivity fluctuations giving 1f noise in bismuth were found to be extremely nonscalar, with local instantaneous anisotropy in between that of dyads and of traceless tensors. This result requires a symmetry-breaking noise-generating mechanism. Temperature dependence and detailed spectral data show that the 1f kinetics are thermally activated and that the net noise magnitude in thick films is a decreasing function of temperature. A crude model accounting for these results is presented.
