Leakage current between two metal transistor electrodes results when the gap between the electrodes narrows to the point that electrons are no longer contained by their barriers — a phenomenon known as quantum tunneling.

Electron tunneling between the wells is controlled by the voltage bias between them and voltage applied to the top control gate. Tunneling Transistor by Quantum Anomalous Spin Hall Effect of Phase Isolator Xiangjiang Li & Teresa Oh; Applied Science and Convergence Technology (2020) Control of tunneling appears to be possible at minimum channel lengths L∼250 Å or less while simultaneously eliminating the need for large‐area source and drain contacts, so that scaling of Si transistors could be significantly extended if this principle proves technically feasible. Single electron transistor: If a pair of conductors, superconductors, or semiconductors are separated by a pair of tunnel barriers (insulator), surrounding a tiny conductive island, like a quantum dot, the flow of a single charge (a Cooper pair for superconductors) may be controlled by a gate. Quantum tunneling isn’t quite an issue just yet. It becomes a serious issue when the gate oxide gets under 2nm in length, which means tunneling becomes a problem at roughly the 5nm node and below. This distance actually changes a bit depending on the exact material used though.
