| Abstract Scope |
We report the initial results of our work on development of microwave and terahertz detectors using AlN/GaN high electron mobility transistors. Microwave measurements (up to 45 GHz) were performed showing that the devices work in a non-resonant mode where responsivity has a quadratic dependence of frequency. Also, the correlation between gate leakage and responsivity was experimentally studied, and a study of the expected performance of one of the measured devices at THz frequencies was carried out, showing the possibility of working at terahertz frequencies with high responsivities even in a non resonant mode. |
