Physics Question on Electronic devices
Silicon can be doped using one of the following elements as dopant:
(A) Arsenic
(B) Indium
(C) Phosphorus
(D) Boron.
To get an n-type semiconductor, the dopants that can be used are______.
Fill in the blank with the correct answer from the options given below.
A
(A) and (C) only
B
(B) and (C) only
C
(A), (B), (C), and (D)
D
(C) and (D) only
Answer
(A) and (C) only
Explanation
Solution
n-type semiconductors are created by doping silicon with Group V elements like arsenic (A) and phosphorus (C). These elements donate electrons, creating the n-type structure. Hence, the correct answer is Option 1.
