enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer

Enhanced Continuous-wave Trahertz emission by nano-electrodes in a photoconductive photomixer Semiconductor materials used as PCA-based photomixers must exhibit high resistivity, high carrier mobility and ultrashort carrier lifetime. Low-temperature-grown GaAs (LT GaAs) has been shown to have such characteristics 14–18 . The samples used in our experiment had a 1-mm-thick LT GaAs layer [...]
