Is Ohm's Law Applicable to Semiconductors in a Magnetic Field?

[MementoMori96]

Is correct to calculate the resistance of a semiconductor sample in a magnetic field with ohm’s law?

 

[Wrichik Basu]

Ohm's Law is for conductors. Semiconductors do not follow Ohm's Law, which is evident from their V-I graph. So Ohm's law cannot be applied to semiconductors under any circumstance.

Outside of the gap voltage, IV (or VI) curves of a typical semiconductor still have Ohmic-like behavior over some range. Of course, this is still governed by a range where resistive heating doesn't come into play and in regions where the carrier density does not change considerably.

Why don't you plot out the IV values? If it is a straight line, then within that range, Ohm's law is valid. If it isn't, then you've gone beyond the validity range.
