GaN Heterodimensional Schottky Diode for THz Detection

The performance of conventional Schottky diodes used for detecting THz radiation is limited by the RC product. Heterodimensional diodes have a smaller capacitance and series resistance. In this paper, we present the first experimental demonstration of THz detection by AlGaN/GaN heterodimensional Schottky diodes (HDSD) that exhibited reasonable performance up to at least 2.24 THz.
