Question

germanium preferred over silicon for makig a semiconductor?

Answer 1

Explanation:

The variation of Collector cut off current with temperature is less in Silicon compared to Germanium. The structure of Germanium crystals will be destroyed at higher temperature.

Answer 2

${\huge {\overbrace {\underbrace {\red{answer}}}}}$
