Which condition hinders gate dielectric scaling due to increased quantum effects?

💡 Explanation

Decreasing oxide thickness increases electron tunneling through the insulating layer, leading to off-state leakage. This increased **quantum tunneling** impacts device performance because electrons pass through the barrier, therefore compromising insulation gate functionality, rather than insulating effectively under bias.
