Increasing the temperature of a semiconductor breaks covalent bonds. For each broken bond, two electrons become free to move and transfer electrical charge. What fraction of the total valance electrons are free to move and what fraction of the covalent bonds must be broken in order that 5×1015 electrons conduct electrical charge in 50 g of silicon?
Discuss the effect of temperature change on interatomic bonds in terms of the type of material. Evaluate the effects of the differences on the thermal analysis data.
