The state of a transistor whereby electrons tunnel across the gate from source to drain even though the gate is not pulsed. As the elements of a chip get smaller, quantum tunneling emerges. Chip designs such as FinFETs and GAAFETs are used to reduce the tunneling effect. See
GAAFET and
transistor.
From Source to Drain
Quantum tunneling generates output at the drain side without the gate being pulsed.
