Schottky Junction Methane Sensors Using Electrochemically Grown Nanocrystalline-Nanoporous ZnO Thin Films
Figure 4
Response versus temperature curves of the (a) Pt/ZnO/Zn, (b) Pd-Ag (26%)/ZnO/Zn, and (c) Rh/ZnO/Zn Schottky sensors in presence of 1% methane in pure nitrogen and in synthetic air, respectively. The response of the sensors is higher in nitrogen than in synthetic air.
