Abstract
Measurements of the second spectra and correlation coefficients of conductance fluctuations are reported for a series of n-type doped a-Si:H films for which the deposition conditions are systematically varied. The non-Gaussian character of the 1/f noise is found to decrease with decreasing deposition temperature, which is also correlated with an increase in the difference between the conductivity and thermopower activation energies (the Q-function). The decrease in non-Gaussian statistics is interpreted as a decrease in the interactions between inhomogeneous current filaments due to increasing long-range disorder in the material.
