Definition: Quantum Tunneling Effect is a quantum mechanical process where particles penetrate through a barrier that they classically would not be able to cross. This intriguing phenomenon plays a ...

A tunnel that can take billions of years to dig, and makes The Shawshank Redemption look like child's play. Mathematically, nonperturbative quantum effects are much more difficult to describe than ...

The chapter also focuses on formulating a mathematical picture that is able to capture the unusual behaviour of quantum particles. It explains the model of tunnel field‐effect transistors (TFETs) for ...

such as the Josephson effect, where a supercurrent can flow through the junction without any applied voltage. SIS junctions are used in superconducting quantum interference devices (SQUIDs), which are ...

The approaches to modelling tunnel field‐effect transistors (TFETs) and quantum devices in general, can be divided into two broad categories: atomistic modelling and analytical modelling. In the case ...

In effect, hydrogen "tunnels" through the activation barrier. Particles of different energies tunnel at various heights. The thinner barrier at the top promotes tunneling, but few particles have ...

We report the spin-dependent quantum well resonant tunneling effect in CoFe/MgO/CoFe/MgO/CoFeB (CoFe) double barrier magnetic tunnel junctions. The dI/dV spectra reveal clear resonant peaks for the ...
