← ScienceWhich bonding change reduces the conductivity of doped silicon?
A)Hydrogen passivation of boron acceptors✓
B)Phosphorus interstitial diffusion acceleration
C)Increased silicon lattice phonon scattering
D)Boron clustering induced carrier depletion
💡 Explanation
Hydrogen passivation occurs because monatomic hydrogen bonds to boron, neutralizing its acceptor attributes; therefore, conductivity decreases, rather than increasing it, because the number of free holes is reduced relative to the initial doping level.
