← ScienceWhich consequence results from increased temperature of silicon?
A)Promotion of electrons to conduction bands✓
B)Increased stability of silicon dioxide
C)Suppression of electron-phonon scattering
D)Formation of stronger sp3 hybrid orbitals
💡 Explanation
Increased temperature causes promotion of electrons to empty conduction bands because thermal excitation provides energy exceeding silicon's band gap via thermal energy, leading to more free carriers. Therefore, intrinsic conductivity rises rapidly, rather than stabilizing oxidation or increasing orbital stability.
