- Abstract
- In this letter, we present low-temperature grown GaAs (LTGGaAs)-based photoconductive antennas for the generation anddetection of terahertz (THz) waves. The growth of LTG-GaAsand the annealing temperatures are systematically discussedbased on the material characteristics and the properties of THzemission and detection. The optimum annealing temperaturedepends on the growth temperature, which turns out to be540¡ÆC to 580¡ÆC for the initial excess arsenic density of2¡¿1019/cm3 to 8¡¿1019/cm3.
