Organic field-effect transistors (OFETs) are emerging as competitive candidates for gas sensing applications due to the ease of their fabrication process combined with ability readily fine-tune properties organic semiconductors. Nevertheless, some key challenges remain be addressed, such material degradation, low sensitivity, and poor selectivity toward toxic gases. Appropriately, a heterojunction combination different layers multifunctional capabilities offers great potential overcome these...
We report an amorphous indium gallium zinc oxide (IGZO)-based toxic gas detection system. The microsystem contains IGZO thin-film transistor (TFT) as a sensing element and exhibits remarkable selectivity sensitivity to low concentrations of nitrogen dioxide (NO2). In contrast existing metal oxide-based sensors, which are active either at high temperature or with light activation, the developed TFT sensor is operable room requires only visible activation revive after exposure NO2....
