Analytical expression for concentration and sensitivity of a thin film semiconductor gas sensor

(in lingua inglese)

The time dependent reaction–diffusion equations in semiconductor gas sensor have been solved analytically and numerically. In the present study, analytical expression corresponding to the concentration profile in semiconductor gas sensor for actual and equivalent model in terms of all reaction parameter, (m) is presented. It is observed that the results obtained using the analytical expression show a good conformity with numerical simulation results.
