What is silicon made of?
Silicon is made from silicon dioxide, or silica – found in nature as quartz, or common beach sand.
First, the silica is put into a Silicon Furnace, where a carbon electrical arc reacts at high temperatures to drive the oxygen out [...]

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 [...]
