Investigation of a GaN-Based SAW Oscillator with respect to UV Illumination and Temperature
Year: 2015
Type: article
Abstract: Oscillation frequency of a GaN-based surface acoustic wave delay-line oscillator is investigated in the temperature range from 20 • C to +38 • C, with and without UV illumination.The results imply that such an oscillator may be used for temperature sensing with the resolution of up to 1 mK.On the other hand, as the frequency downshift due to UV illumination does not exhibit a signicant dependence on temperature, it may be expected that such a system, when used as a UV sensor, would not require applying a correction for temperature.
