Abstract

Dynamical current redistribution (DCR) in noisy resistors is discussed. Contrary to a common assumption in many theories and in the interpretation of many experiments, DCR can cause large-amplitude non-Gaussian (NG) noise for statistically independent fluctuators. NG effects are predicted to be large near the percolation threshold and near the metal-insulator transition. We report the first observations of NG noise in semiconductor superlattices and attribute this to DCR. We also show that DCR is the most likely explanation of NG noise in several other systems.
