← ScienceWhich outcome occurs when a semiconductor device drops below the inversion threshold?
A)Channel electron depletion occurs✓
B)Increased electron-hole recombination
C)Electron mobility sees peak value
D)Metallic bonds are permanently weakened
💡 Explanation
Channel electron depletion occurs because insufficient gate voltage prohibits the surface from inverting, resulting in the electrostatic repulsion of electrons rather than attraction via field-effect; therefore a depletion region forms, rather than electron accumulation.
