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 [...]
When it comes to choosing a material as the basic material for transistors in computers, the key matter we need to consider is resistance. Conductors have very low resistance and can conduct electricity easily; insulators have high resistance and cannot conduct electricity. For transistors, [...]
