Question
Physics Question on Semiconductor electronics: materials, devices and simple circuits
The electron concentration in an n-type semiconductor is the same as the hole concentration in a p-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them
A
No current will flow in p-type, current will only flow in n-type
B
current in n-type=current in p-type
C
current in p-type > current in n-type
D
current in n-type > current in p-type
Answer
current in n-type > current in p-type
Explanation
Solution
The correct answer is option (D) : current in n-type > current in p-type
