Hall Voltage in a Heated Semiconductor
The Hall voltage measured across a semiconductor device reverses its sign when the device is significantly heated. This observation most likely indicates that:
A
The conductivity of the material decreased to zero
B
The magnetic field direction spontaneously reversed
C
The dominant charge carriers changed from electrons to holes
D
The charge carriers gained enough energy to overcome the Hall effect
