Quantum tunneling is projected to create physical limits to the size of the transistors used in microelectronics, due to electrons being able to tunnel past transistors that are too small. Tunneling may be explained in terms of the Heisenberg uncertainty principle in that a quantum object can be known as a wave or as a particle in general.

known as quantum tunneling. 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.

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 .

If any internal barriers get thinner than a nanometer, too much current will tunnel through when the transistor From Wikipedia, the free encyclopedia 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. transistors, tunnelling occurs with barriers of thickness around 1-3 nm and smaller in which the gate is controlled via quantum tunnelling rather than by thermal injection, reducing gate voltage from ∼1 volt to 0.2 volts and reducing power consumption by up to 100x.

Rapid Detection of Coherent Tunneling in an Nanowire Quantum Dot through Dispersive quasiparticle dynamics of nanowire single-Cooper-pair transistors.

Introducing the Quantum Law of 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. “These quantum effects become important in silicon if the transistor body dimension is at or below about 7nm.” As gate length is gradually reduced to accommodate scaling, the consequences show up in two main places. One is in the transistor OFF state, where carriers can more easily tunnel from the source-drain. Scientists at Michigan Technological University made the quantum-tunneling device, which behaves like a transistor at room temperature, without using any semiconducting materials. Credit: Yoke Khin A distinctive feature of a tunneling transistor is its very strong sensitivity to control voltage.
