Holes N-type Semiconductor are
Right Answer is:
Minority carriers produced by thermal energy
Holes in N-type semiconductors are minority carriers produced by thermal energy.
⇒ The n-type semiconductor is formed by doping a pure silicon or germanium crystal with a material having five valence electrons.
⇒ In N-type semiconductors, electrons (negative charges) are the majority carriers, but the semiconductor doped with impurity remains electrically neutral.
⇒ Free electrons and holes are generated in pairs due to thermal energy and the negative charge of electrons donated by impurity atoms is exactly balanced by the positive charge of the immobile ions.
⇒ Hence in n-type material, the electrons become the majority carriers and the holes generated by thermal energy constitute minority carriers.
