Question

Why silicon is preferred over germanium as a semiconductor material?

Answer 1

Answer:

First of all..... silicon is less expensive due to the greater abundance of elements and silicon crystal has fewer free electrons than germanium and are also not easily damaged by heat.

Hope it helps.

At room temperature, Silicon crystal has fewer free electrons than Germanium crystal. However, Silicon crystals are not easily damaged by excess heat. Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance of element.
