The conductivity of a photosensitive semiconductor depends on?

Open in App

Solution

Conductivity:
It is the ability of a material to allow heat and electricity to pass through it.
It works with both the physical movements of electrons and the transfer of energy between the electrons.
There are various types of conductivities like electrical, thermal, ionic, and acoustic.
A simple example is the heat transfer to the spoon from a hot bowl of soup.
The bulbs and other lamps in our house glow because the wires connected to the bulb conduct electricity.
Conductivity is inversely proportional to resistivity.
When light is allowed to fall on a semiconductor, it gets heated up.
Because the temperature coefficient of resistivity, $α$ of semiconductor, is negative, Thus increasing the temperature will decrease the resistance.
Thus, the conductivity of a photosensitive semiconductor depends upon the light falling on it.
