High-k, Quantum Mechanical Tunneling and Gate Leakage. Gate leakage in a modern transistor occurs through a process called "quantum mechanical tunneling." Under normal circumstances, all the electrons are on the "upstream" side of the gate (picture the gate as a dam, and electrons as water trapped behind the dam).

Credit: Yoke Khin The tunnel field-effect transistor (TFET) is an experimental type of transistor. Even though its structure is very similar to a metal-oxide-semiconductor field-effect transistor ( MOSFET ), the fundamental switching mechanism differs, making this device a promising candidate for low power electronics. TFETs switch by modulating quantum tunneling The Tunneling Transistor | Quantum Neuroscience. For example, Imec’s Mocuta points to transistor body scaling, which is gradually becoming a requirement for maintaining electrostatic control. Quantum effects show up as thinner fins, which ultimately will force a move to gate-all-around transistor structures using nanowires or nanosheets. That move isn’t far off. The double-layer tunneling transistor, or Deltt, is a planar device consisting of two 15-nm-thick quantum wells separated by a 12.5-nm-thick barrier.

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.

But it could also the path forward…Our always-on world of PCs, tablets, and smartphones has come about because of one remarkable trend: the relentless miniaturization of the metal-oxide-semiconductor field-effect-transistor, or MOSFET. 2020-06-11 · The surface current of a phase isolator has been reported to be capable of creating quantum tunneling phenomena due to quantum confinement effects 12,13,14. A quantum tunneling transistor which provides two switching inputs, for example source and drain as with a conventional FET, and a control input which, in one embodiment, performs much like the 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.

Since particles behave like probabilities, they have non-zero chances of being most anywhere. This is actually observed in ordinary computing, where it sets the floor for transistor size. Quantum tunneling. Credit: Daria Sokol, MIPT Press Office. The sensitivity of the device is already superior to commercially available analogs based on semiconductors and superconductors, which opens up prospects for applications of the graphene detector in wireless communications, security systems, radio astronomy, and medical diagnostics.

Even a small “detuning” of energy levels is enough to interrupt the subtle process of quantum mechanical tunneling. Similarly, a small voltage at the control gate is able to “connect” the levels and initiate the tunneling current.

As chipmakers have squeezed ever more transistors onto a chip, transistors have gotten smaller, and the distances between different transistor regions have decreased. So today, electronic barriers that were once thick enough to block current are now so thin that electrons can barrel right through them.
