Electrical and Photovoltaic Properties of In-pSi Contact [PDF]

open access: yesEngineering and Technology Journal, 2007
In the present work, the electrical and photovoltaic properties of In-pSi contact were investigated for the first time. Two creditable methods were used to determine the value of barrier height for this contact.

Macro-microscopic Calculation of Five-dimensional Potential Energy Surface for 234U Fission

open access: yesYuanzineng kexue jishu, 2022
A key question about the fission process of a heavy nucleus is to probe the nuclear potential energy landscape and its evolution from the single groundstate compound nucleus over the top of the fission barrier and further to the scission point, finally ...

Height of the Potential Barrier in Barrier Layer Cells [PDF]

open access: yesNature, 1953
Measurements of the zero resistance of a number of barrier-layer cells1 over a wide range of temperatures have shown that the theoretical expression: where A and ϕ are regarded as constants, is not obeyed over the whole range of temperatures.

Intestinal barrier function and absorption in pigs after waeaning: a review

open access: yes, 2011
Under commercial conditions, weaning of piglets is associated with social, environmental and dietary stress. Consequently, small-intestinal barrier and absorptive functions deteriorate within a short time after weaning.

Modelling of Low-Voltage Varistors’ Responses under Slow-Front Overvoltages

open access: yesElectronic Materials, 2023
In this study, commercially low-voltage MOVs are exposed to switching surges to analyse and model the relationship between the number of surges and the MOV grain barrier height response.

Barrier heights in the Kauffman model

open access: yesJournal de Physique, 1989
We consider two versions of the Kauffman model (the quenched and the annealed models) in presence of thermal noise. When we compare the time evolution of two configurations subjected to the same thermal noise, we find for both versions of the Kauffman model that below a critical temperature T c, the time τ2 for these two configurations to become ...

Understanding Density-Driven Errors for Reaction Barrier Heights

open access: yesJournal of Chemical Theory and Computation, 2023
Delocalization errors, such as charge-transfer and some self-interaction errors, plague computationally-efficient and otherwise-accurate density functional approximations (DFAs). Evaluating a semi-local DFA non-self-consistently on the Hartree-Fock (HF) density is often recommended as a computationally cheap remedy for delocalization errors.
