Computationally efficient quantum-mechanical technique to calculate direct tunnelling gate leakage current in metal-oxide-semiconductor structures

, 2003
We propose a computationally efficient, accurate and numerically stable quantum- mechanical technique to calculate the direct tunneling (DT)gate current in metal-oxide-semiconductor (MOS) structures.

Spin-Degenerate Regimes for Single Quantum Dots in Transition Metal Dichalcogenide Monolayers

, 2017
Strong spin-orbit coupling in transition metal dichalcogenide (TMDC) monolayers results in spin resolvable band structures about the $K$ and $K'$ valleys such that the eigenbasis of a 2D quantum dot (QD) in a TMDC monolayer in zero field is described by ...

Migrant Organisations on the Rise after 2015/2016? Between “Projectitis” and the Formation of New Structures and Types

Social Sciences
The paper departs from the observation that the role of migrant organisations (MOs) in Germany has changed significantly since the strong influx of refugees in 2015/16.

Spatial and Electronic Manipulation of Silicon Nanocrystals by Atomic Force Microscopy [PDF]

, 1998
[As silicon-based devices shnnk, interest is increasing in fast, low-power devices sensitive to small numbers of electrons. Recent work suggests that MOS structures with large arrays of Si nanocrystals comprising a floating gate can be extremely fast ...

Study of $N\left(1440\right)$ structure via ${\gamma }^{*}p\to N\left(1440\right)$ transition

Physical Review, 2022
We study the γ*p→N* transition of the N(1440) resonance in quark models to reveal the inner structure of the resonance. The N(1440) is assumed in the study: (a) the first radial excitation of the nucleon, where the quark distribution is imported from low-lying baryon mass spectrum calculations, (b) a general radial excitation of the nucleon, and (c) a ...

Nanocatalysis MoS₂/rGO: An Efficient Electrocatalyst for the Hydrogen Evolution Reaction

Molecules
In this study, a systematic investigation of MoS2 nanostructure growth on a SiO2 substrate was conducted using a two-stage process. Initially, a thin layer of Mo was grown through sputtering, followed by a sulfurization process employing the CVD ...
