Question

If light shining on a semi-conductor generates electrons as well as heat in the semi-conductor, how can we find the rate of heat energy per unit volume produced due to this light source in a semi-conductor?​

Answer 1

if a light is shining on a semiconductor it generates electron as well as heat in the semiconductor.

Explanation:

• The energy which is possesed by the electron is due to the kinetic energy of the electron. By measuring the velocity of the electron at which the electrons are projected out we can find the kinetic energy= 1/2mv² where m is the mass of the  electron

• The total heat energy= light energy given -1/2mv²

• The heat energy per unit volume is  given by the equation, heat energy per unit volume= heat energy/ volume of the semiconductor
