Which outcome occurs due to exceeding silicon's band bending limit?

💡 Explanation

Increased surface electron-hole recombination occurs if the band bending approaches the bandgap because of increased carrier density at the surface promotes annihilation via Shockley-Read-Hall recombination. Therefore, surface trapping becomes prominent, rather than influencing doping or bulk properties.
