Electrons and holes can recombine at the surface of a semiconductor. O 2. Electrons and holes can recombine at traps in the energy.gap and close to the minimum in the conduction band. O 3. Electrons in the conduction band can annihilate holes in the valence band and vice-versa. O 4. Electrons and holes can recombine at traps in the energy gap and close to the maximum in the valence band. O 5. Electrons and holes can recombine with an Auger process. O 6. Electrons and holes can recombine at traps located in the middle of the energy gap.
