A semiconductor is formed by __________ bonds.

A semiconductor is formed by __________ bonds.

Right Answer is:

Covalent

SOLUTION

  • A semiconductor atom having four valence electrons and four holes require four more electrons so as to make the outermost orbit completely filled (total number must be eight).
  • Each atom that is normally bonded with the nearest neighbor atoms results in a special shape called a crystal.
  • A silicon atom that is a part of a crystal has eight electrons in the valence orbit and four neighbor atoms.
  • Each of the four neighbors shares one electron. Since each shared electron is being pulled in opposite directions, it is a kind of a bond between the opposite cores.
  • This type of bond is known as a covalent bond. The covalent bonds hold the tetravalent crystal together, ensuring its stability.
