- Abstract
Chemisorption processes significantly influence the surface states of semiconductor films. It is assumed that these processes should also influence electric-current noise generated by the semiconductor structure. We study stationarity and Gaussianity of the resistance fluctuations of semiconductor gas sensors. It is shown that Gaussianity and stationarity of noise are shown as functions of the gas-phase composition and temperature. On this basis, we conclude that it is in principle possible to increase the selectivity of gas sensors by jointly measuring their sensor and noise characteristics.
