Expert Answer:

Silicon is preferred to germanium in the manufacture of semiconductor devices (e.g. semiconductor diode, transistor, etc.) due to the following reasons:-

(i)                 The leakage current in silicon is very small as compared to that of germanium.

(ii)             The working temperature of silicon is more than that of germanium. The structure of germanium will be destroyed at a temperature of about 1000C. However silicon can be operated up to about 2000C.
