SnO,-gate FETs with ammonia-sensing behaviour are investigated at constant ammonia concentration (100 ppm) and different bias conditions. Strong dependence of the sensing behaviour on the drain and gate voltage (Vn, Vo) applied is observed. The current response obtained could be positive, negative o
