Aharonov-Bohm Oscillations in a One-Dimensional Wigner Crystal-Ring

open access: yes, 1994
We calculate the magnetic moment (`persistent current') in a strongly correlated electron system --- a Wigner crystal --- in a one-dimensional ballistic ring.

The vertical metal insulator semiconductor tunnel transistor: A proposed Fowler-Nordheim tunneling device

open access: yes, 2005
We propose a new field-effect transistor, the vertical metal insulator semiconductor tunnel transistor (VMISTT) which operates using gate modulation of the Fowler-Nordheim tunneling current through a metal insulator semiconductor (M-I-S) diode.

Barrier height distributions – the influence of weak channels

open access: yesEPJ Web of Conferences, 2011
The barrier distributions for the 20Ne+58,60,61Ni systems were experimentally determined. In the 58Ni case one observes a distinct “structure” in the distribution (two peaks) which is partially damped for 60Ni and completely smoothed out for 61Ni.

Electric-field-driven polymer entry into asymmetric nanoscale channels

open access: yes, 2012
The electric-field-driven entry process of flexible charged polymers such as single stranded DNA (ssDNA) into asymmetric nanoscale channels such as alpha-hemolysin protein channel is studied theoretically and using molecular dynamics simulations ...

Temperature dependence of barrier height in a Ni/β-Ga2O3 Schottky barrier diode precisely determined by the analysis based on the thermionic emission-diffusion model

open access: yesApplied Physics Express
Temperature dependence of the barrier height in a Ni/ β -Ga _2 O _3 Schottky barrier diode has been investigated in 303–573 K. The barrier height obtained by the capacitance–voltage ( C – V ) measurements slightly decreased with increasing temperature ...

Superposition states of ultracold bosons in rotating rings with a realistic potential barrier

open access: yes, 2011
In a recent paper [Phys. Rev. A 82, 063623 (2010)] Hallwood et al. argued that it is feasible to create large superposition states with strongly interacting bosons in rotating rings.

Woods-Saxon equivalent to a double folding potential

open access: yes, 2015
A Woods-Saxon equivalent to a double folding potential in the surface region is obtained for the heavy-ion scattering potential. The Woods-Saxon potential has fixed geometry and was applied as a bare potential in the analysis of experimental data of ...

Extended active space CASSCF/MRSD CI calculations of the barrier height for the reaction: O + H2 yields OH + H [PDF]

open access: yes
The convergence of the barrier height for the O + H2 yields OH + H reaction was studied as a function of the size of the active space and basis set completeness.

Intercalating cobalt between graphene and iridium (111): a spatially-dependent kinetics from the edges

open access: yes, 2017
Using low-energy electron microscopy, we image in real time the intercalation of a cobalt monolayer between graphene and the (111) surface of iridium. Our measurements reveal that the edges of a graphene flake represent an energy barrier to intercalation.

Quantum wells, wires and dots with finite barrier: analytical expressions for the bound states

open access: yes, 2002
From a careful study of the transcendental equations fulfilled by the bound state energies of a free particle in a quantum well, cylindrical wire or spherical dot with finite potential barrier, we have derived analytical expressions of these energies ...
