Abstract
ALD grown MoS2 nanofilm on TiO2 nanotubes support were studied as NO2 gas sensor. In addition to traditional relative resistance response, we show that a rarely studied first-order derivative response is an excellent alternative with monotone dependency on concentration and fast response time, avoiding the need for long gas exposure periods to achieve high and stable sensor response.
