Questions
Statement I: Silicon is preferred over germanium for making semiconductor devices.
Statement II: The energy gap for germanium is more than the energy gap of silicon.
detailed solution
Correct option is B
The energy gap for germanium is less (0.72 eV) than the energy gap of silicon ( 1.1 eV). Silicon is preferred over germanium for making semiconductor devices because they are abundantly available in nature, do not get easily damaged by heat and cut off current is very low.Talk to our academic expert!
