Abstract
Hydrogen sensors based on AlGaN/GaN back-to-back Schottky diodes have been produced.Platinum is sputtered on the surface of the sample.The response of the device to 10% H2 in N2 is measured at 25~100℃.The oxygen in the air has great influence on the current of the device.Finally,the variation of the Schottky barrier height induced by the hydrogen is calculated.-
