Answer / inchara

Impurities can affect the properties of Electrical
(silicides) directly by virtue of their presence.

Answer / satheesh

The impurities make changes with the number of holes and
electrons,and also the conductivity,as the resistance
increases conductivity decreases.

Answer / engr. nahid

Impurities are having a special properties of good
conductivity. When small amount of impurities added in
semiconductor type material, this conductivity is then
counted as the whole semiconductors conductivity. Thus
increasing conductivity of the semiconductor. Usually a
small amount 0.1% to 1% impurities a enough to get proper
conductivity of the material on which this need to increased.
