Question

A block of semiconductor material that is 1mm in transverse width has a magnetic field 0.5T vertically downward through it, and the Hall voltage is 50mV. Find the drift speed of the carriers.
Options
A 13.5 m/s
Correct Answer
B 20 m/s
C 1 m/s
D 100 m/s
Correct Answer

Option A is the correct answer.

Detailed Explanation

Using the Hall voltage relation V_H = Bvd (with d the relevant width) and solving for v gives a drift speed of approximately 13.5 m/s.

Hint

Rearrange the Hall voltage formula V_H = Bvd to solve for the drift velocity v.
