Abstract Single crystal nanobelts of ZnO were synthesized and deposited onto 36° YX LiTaO3 and 64° YX LiNbO3 surface acoustic wave (SAW) devices for gas sensing applications. Sensor response, defined as the change in resonant frequency, was measured for H2 and NO2 between 20 and 200°C. Measured sensor responses were 3.5 kHz towards 10 ppm NO2 for a 64° LiNbO3 SAW transducer operating at 160°C and 3 kHz towards 1% H2 for a 36° LiTaO3 SAW transducer operating at 185°C temperature.
