* As a result of such considerations, and other direct band gap semiconductors are used to and semiconductor lasers, whereas silicon, which is an indirect band gap semiconductor, is not. *But fl a crushing commercial advantage, Silicon is abundant in the earth crest. It is roughly a_ ‘Silicon fer diode ==> At room temperature, Silicon crystal has fewer free electrons than: | aa This implies that silicon will have much smaller Collector cut off current than ‘Silicon crystallizes in @ diamond form with relatively strong bond gaining the crystals relatively sitong mechanical properties which is advantageous for mechanical handling and processing. *The e relativel *Silicon dioxide is used also as an insulator and passivation layer. of about one 10*10/cm*3. Which is *Silicon has relatively high dielectric strength and therefore is suitable for power devices.
