The Solid State - Result Question 35
####35. With which one of the following elements silicon should be doped so as to give $p$-type semiconductor?
[2008]
(a) Germanium
(b) Arsenic
(c) Selenium
(d) Boron
Show Answer
Solution:
- (d) The semiconductors formed by the introduction of impurity atoms containing one elecron less than the parent atoms of insulators are termed as $p$-type semiconductors. Therefore, silicon containing 14 electrons has to be doped with boron containing 13 electrons to give a $p$-type semi-conductor.
