Titel
Improved InGaAs/InAlAs photoconductive THz receivers: 5.8 THz bandwidth and 80 dB dynamic range
Abstract
We investigate optimal Be-doping conditions of low-temperature-grown InGaAs/InAlAs photoconductive antennas with respect to their carrier lifetimes and carrier mobility. Employed as THz-TDS receiver bandwidths of 5.8 THz with a dynamic range of up to 80 dB is achieved.
