W is a function of applied voltage across the junction V. The derivation of Equation 6-27 is based on the following assumptions (Schottky model): The barrier height ϕB is large compared with kT. Nd(ionized)=constant for 0<x<W,and Nd(ionized)W≫∫owndx,Nd(ionized)>...
The anisotropy in resonant tunneling transport through an electrostatic barrier in monolayer black phosphorus either in presence or in absence of an oscillating potential is studied. Non-perturbative Floquet theory is applied to solve the time dependent
a weakly dopedp−-porous layer and ap−/ppotential barrier at the porous/capping interface. The effectivep−doping concentration of the porous layer is expected to be relatively low, so that the field extends across the entire porous layer. Because of the small sizes (∼20–30 nm)...

As briefly discussed in Section 2.2., Kubby, Wang and Greene [61] and later also Yang et al. [62] showed that the FER scanning tunneling spectroscopy technique can also be applied to systems that involve a substrate/vacuum interface as well as a subsurface interface barrier. These systems ...
The integrity of the epithelial barrier was determined over 48 h by TEER measurements. In addition, the effect of EGCG on the immune cells was investigated by analysis of the cytokine release. The cell viability of the epithelial and immune cells was determined to investigate possible cytotoxic ...
There are several possible mechanisms by which nicotine could cause toxicity in human keratinocytes, including the stimulation of nicotine-like acetylcholine receptors (nAChRs), thereby altering the skin’s barrier function [30]. There is evidence that nicotine exposure increases the levels of alpha7 ...
