Theory of power laws for semiconductor gas sensors
Noboru Yamazoe,Kengo Shimanoe +1 more
TL;DR: In this paper, the authors derived a theoretical basis for power laws of gas sensors by combining a depletion theory of semiconductor, which deals with the distribution of electrons between surface state (surface charge) and bulk, with the dynamics of adsorption and/or reactions of gases on the surface, which is responsible for accumulation or reduction of surface charges.
