what is the use of silicon in semiconductor
Although some pure elements and many compounds display semiconductor properties, silicon, germanium, and compounds of gallium are the most widely used in electronic devices. Elements near the so-called metalloid staircase, where the metalloids are located on the periodic table, are usually used as semiconductors.he semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p-and n-type dopants. A single semiconductor crystal can have many p-and n-type regions; the pân junctions between these regions are responsible for the useful electronic behaviour.
