The advantage of using silicon over germanium at higher temperatures.
Explanation of Solution
Introduction:
The valence band contains electrons in the valence shell which are not free to move. When energy is supplied, the electrons in the valence band move to
Although silicon has a higher band gap than germanium resulting in lesser thermally generated free electrons, silicon is superior for high temperature applications because the maximum normal working temperature for germanium is around after which its structure is destroyed whereas silicon can be operated up to and are not easily damaged by heat.
Conclusion:
Silicon is superior for high temperature applications because the maximum normal working temperature for germanium is around after which its structure is destroyed. On the other hand silicon can be operated up to and are not easily damaged by heat.
