Question

if hall voltage is zero when the semiconductor is​

Answer 1

Explanation:

We can easily identify whether a semiconductor is p-type or n-type by using Hall Effect. If the voltage produced is positive then the material is said to be p-type and if the voltage produced is negative then the material is said to be n-type.

Answer 2

If hall voltage is zero when the semiconductor is intrinsic.

• Hall effect depends on conductivity and conductivity depends on mobility.
• The mobility of electrons is more than the holes.
• The semiconductor is intrinsic when the hall voltage is zero because the concentration of holes and electrons are the same in this type of semiconductor.
• Hall effect is the production of voltage difference which is called the hall effect.
