Which mechanism causes increased electron leakage when the gate oxide thickness in a MOSFET approaches quantum limits?

💡 Explanation

Electron leakage increases because quantum tunneling probability increases exponentially as the oxide thickness decreases; therefore electrons can tunnel through the decreasing barrier rather than being confined, with thermal fluctuations being much smaller under such small sizes.
