The tunneling time is smaller in space fractional quantum mechanics as compared to the case of standard quantum mechanics. We recover the Hartman effect of standard quantum mechanics as a special case of space fractional quantum mechanics.doi:10.1016/j.physleta.2017.12.002Mohammad Hasan...
Tunneling is one of several effects in quantum mechanics that defies explanation in terms of the “classical” physics that preceded it. Quantum mechanics says that there is a tiny probability that a particle shot at a wall will pass through it in an effect known as tunneling. In QTC, th...

Definition Quantum mechanical tunneling is the penetration of a particle into a region forbidden in classical mechanics as the particle lacks the energy to reach it. The phenomenon of tunneling is a quantum mechanical effect: it can only be explained when the wave-like nature of matter is ...
As mentioned in previous sections, the electron tunneling is the first step of many strong field processes. Actually, as a purely quantum effect, quantum tunneling represents one of the triumphs in quantum mechanics. The tunneling effect refers to the penetration of matter waves or transmission of...
This is caused by the tunnel effect: “Quantum mechanics allows particles to break through the energetic barrier due to their quantum mechanical wave properties, and a reaction occurs,” explains the first author of the study, Robert Wild. “In our experiment, we give possible reactions in the...
A consistent theory of superconductive tunneling in single-mode junctions within a scattering formulation of Bogolyubov-de Gennes quantum mechanics is presented. The dc Josephson effect and the dc quasiparticle transport in the voltage-biased junctions are considered. Elastic quasiparticle scattering by ...
Tunneling phenomenon is one of the most remarkable and unique consequences of the wave nature of particles in quantum mechanics, where a particle can penetrate through classically forbidden regions. In solids, the quantum mechanical wavefunctions of electrons form the band structure separated by the en...
Quantum tunneling plays a crucial role in physical phenomena, such as nuclear fusion. It has various applications in the working of the tunnel diode, quantum computing, and in the scanning tunneling microscope, etc... The effect was predicted and demonstrated in the early 20th century. Its accep...
The continuously intensifying demand for high-performance and miniaturized semiconductor devices has pushed the aggressive downscaling of field-effect transistors (FETs) design. However, the detrimental short-channel effects and the fundamental limit on
