Why silicon is a semiconductor and not a metal?

Because of these 4 valence electrons, silicon always forms covalent bonds with other compounds. Due to the properties of a metalloid, it acts as a semiconductor. Semiconductors are materials that have an energy difference between the covalent band and the valence band between metals and nonmetals.

Why is silicon preferred over germanium for semiconductors? This is because silicon can be processed at a higher temperature than germanium. The crystal structure of germanium is destroyed at higher temperatures. Also, silicon has a much lower leakage current than germanium.

Why are chips called semiconductors?

Silicon is the material of choice in the chip industry. Read also : When did transistors replaced vacuum tubes?. Unlike the metals commonly used to conduct electricity, silicon is a “semiconductor,” meaning that its conductive properties can be increased by mixing it with other materials such as phosphorus or boron.
