← ScienceWhich limit emerges when applying high gate voltage?
A)Dielectric material electric field breakdown✓
B)Quantum mechanical work function penetration
C)Channel length thermal diffusion widening
D)Electron-phonon coherent momentum scattering
💡 Explanation
If excessive electric field exceeds the limits, dielectric breakdown will occur, because the electric field strength surpasses the dielectric's ability to withstand it triggering material ionization, therefore current flows destroying dielectric insulation, rather than work function penetration, which requires significant tunneling and specific materials.
