Electron tunneling through barriers of adjustable width: Role of the image potential and the wetting behavior of Cs by He [PDF]
Physical Review B, 2008 Photocurrents from cesium, flowing through gaseous 3 He or 4 He and also through thin liquid helium films, are investigated as a function of the chemical potential of helium at T = 1.33 K. At low pressures, the two isotopes behave similarly as the photocurrent is governed by scattering by the gas. At higher pressures, a film of 3 He grows on the Cs and

Low temperature tunneling current enhancement in silicide/Si Schottky contacts with nanoscale barrier width [PDF]
Applied Physics Letters, 2011 The low temperature electrical behavior of adjacent silicide/Si Schottky contacts with or without dopant segregation is investigated. The electrical characteristics are very well modeled by thermionic-field emission for nonsegregated contacts separated by micrometer-sized gaps.

Tunneling time and Hartman effect in a ferromagnetic graphene superlattice
AIP Advances, 2012 Using transfer-matrix and stationary phase methods, we study the tunneling time (group delay time) in a ferromagnetic monolayer graphene superlattice. The system we peruse consists of a sequence of rectangular barriers and wells, which can be realized by

Concept for a fractional energy barrier tunneling junction
, 2023 In general, the tunnel current in field emission tunneling junctions is determined by the barrier height under an applied electric field. Introducing an alternative way to modulate the tunnel current other than tuning the barrier height is important for ...

Barrier tunneling of quasiparticles in double-Weyl semimetals
, 2020 We investigate barrier tunneling of quasiparticles in double-Weyl semimetals. Being the anisotropic dispersion, it exhibits different scattering properties for different barrier orientations. We discuss two cases.
