← ScienceWhich mechanism limits the performance of microelectronic devices due to electrons?
A)Quantum tunneling bypassing insulation barrier✓
B)Increased electron-phonon scattering raises resistance
C)Increased Cooper pair formation decreases current
D)Increased electron-electron repulsion exceeds voltage
💡 Explanation
Quantum tunneling causes electrons to pass through classically forbidden regions in semiconductors, because the wave function has a non-zero probability. This unwanted leakage increases power consumption; therefore performance is limited, rather than by resistance or repulsion at standard operating voltages.
