Controlling Drain Side Tunneling Barrier Width in Electrically Doped PNPN Tunnel FET. [PDF]

Micromachines (Basel), 2023
In this paper, we propose and investigate an electrically doped (ED) PNPN tunnel field effect transistor (FET), in which the drain side tunneling barrier width is effectively controlled to obtain a suppressed ambipolar current.

Absence of Additional Stretching‐Induced Electron Scattering in Highly Conductive Cross‐linked Nanocomposites with Negligible Tunneling Barrier Height and Width

Advanced Science
The intrinsic resistance of stretchable materials is dependent on strain, following Ohm's law. Here the invariable resistance of highly conductive cross‐linked nanocomposites over 53% strain is reported, where additional electron scattering is absent ...

Drain Induced Barrier Widening and Reverse Short Channel Effects in Tunneling FETs: Investigation and Analysis

IEEE Access, 2021
In this paper, using calibrated TCAD simulations, we demonstrate how the performance of a Tunneling FET (TFET) can be improved by using a new phenomenon called drain induced barrier widening (DIBW) at the source-channel junction.

A general scenario of tunneling time in different energy regimes [PDF]

New Journal of Physics, 2022
We theoretically study the tunneling time by investigating a wave packet of Bose-condensed atoms passing through a square barrier. We find that the tunneling time exhibits different scaling laws in different energy regimes.

Supercontinuum Generation from Airy-Gaussian Pulses in Photonic Crystal Fiber with Three Zero-Dispersion Points

Photonics, 2023
The supercontinuum generation and manipulation of Airy-Gaussian pulses in a photonic crystal fiber with three zero-dispersion points are studied using the split-step Fourier method. Firstly, the spectral evolution of Airy-Gaussian pulses in four photonic

Multiple Fano Resonances in Dynamic Resonant Tunneling Processes

Applied Sciences, 2023
The existence of Fano resonances in dynamic resonant tunneling (RT) systems has been investigated. Fano resonances are characterized by the appearance of a 100% reflection coefficient in proximity to a high transmission coefficient.
