Silicon doped with aluminum and germanium doped with arsenic become?
-
A.
p- and n- types respectively -
B.
n- en p- type respectively -
C.
p- type semiconductor -
D.
n- type semiconductors
Correct Answer: Option A
Explanation
When silicon, a four valency element, is doped with aluminum, a three valency element, a p-type semiconductor is produced where the major carriers are the electrons.
Thus, the correct option is p-type and n-type respectively
