Question

write about the Semiconductors​

Answer 1

Answer:

Electrical conductivity of a semiconductor material is intermediate between that of metals and insulators. The metalloids Si and Ge are semiconductors Like insulators, the valence band in semiconductor is completely filled with electrons and conduction band is empty.

However, the energy gap between the two bands is smaller than that in an insulator.

Answer 2

solid substance that allows heat or electricity to pass through it or along it in particular conditions

अर्धचालक (विशिष्‍ट दशाओं में ताप या विद्युत का चालन करने वाला एक ठोस पदार्थ); सेमिकंडक्‍टर
