Doping of a Semiconductor
Doping is the process by which adding an impurity into a pure form of semiconductor (intrinsic semiconductor) to improve its electrical characteristics (or) conductivity.
DOPING
OF A SEMICONDUCTOR
Doping
is the process by which adding an impurity into a pure form of semiconductor
(intrinsic semiconductor) to improve its electrical characteristics (or)
conductivity.
Process
of doping:
(i)
Melt the pure semiconductor crystal Si (or) Ge
(ii)
Molten crystal in the liquid form and it breaks the covalent bonds
(iii\)
To increase the number of electron, pentavalent atoms are added as impurity in
the molten silicon.
(iv)
Impurity will donate an electorn to the silicon crystal, thus it is called as
donor impurities.
(v)
To increase the number of holes, trivalent atoms are added as impurity in the
molten silicon.
(vi)
These impurity will accept an electron, hence these impurities are called as
acceptor impurities.
