In this paper, we investigated the effect of the central AlGaAs barrier width Lb2 in a resonant tunneling diode (RTD) composed by triple barriers on the current-voltage characteristics, and electronic density of free carriers.

Tunneling time and Hartman effect in a ferromagnetic graphene superlattice
Using transfer-matrix and stationary phase methods, we study the tunneling time (group delay time) in a ferromagnetic monolayer graphene superlattice. The system we peruse consists of a sequence of rectangular barriers and wells, which can be realized by

How large is the spreading width of a superdeformed band? [PDF]
Recent models of the decay out of superdeformed bands can broadly be divided into two categories. One approach is based on the similarity between the tunneling process involved in the decay and that involved in the fusion of heavy ions, and builds on the

Accelerating Quantum Decay by Multiple Tunneling Barriers
A quantum particle constrained between two high potential barriers provides a paradigmatic example of a system sustaining quasi-bound (or resonance) states.

To test the quality of a tunnel junction, one sometimes fits the bias-dependent differential conductance to a theoretical model, such as Simmons's formula.

Vacuum decay and the transmission resonances in space-dependent electric fields [PDF]
We investigate the decay of quantum electrodynamical (QED) vacuum in arbitrary space-dependent electric fields. In particular, we analyze the resonance peaks of the positron emission spectrum for the external fields with subcycle structure.

Exploiting Within-Channel Tunneling in a Nanoscale Tunnel Field-Effect Transistor
In this paper, using device simulations, we investigate electrical characteristics of a tunnel field-effect transistor (TFET) in which band-to-band tunneling (BTBT) occurs dominantly within the channel, rather than at source-channel junction.
