Electron tunneling time measured by photoluminescence excitation correlation spectroscopy [PDF]
, 1989 The tunneling time for electrons to escape from the lowest quasibound state in the quantum wells of GaAs/AlAs/GaAs/AlAs/GaAs double-barrier heterostructures with barriers between 16 and 62 Å has been measured at 80 K using photoluminescence excitation ...

Frontiers in Earth Science, 2019 Ancient barrier islands are poorly understood relative to other clastic depositional environments, despite being prominent features along modern coastlines and important for understanding transgressive shoreline deposits. A new dataset of ancient barrier

Precise engineering of quantum dot array coupling through their barrier widths [PDF]
Nature Communications, 2017 AbstractQuantum dots are known to confine electrons within their structure. Whenever they periodically aggregate into arrays and cooperative interactions arise, novel quantum properties suitable for technological applications show up. Control over the potential barriers existing between neighboring quantum dots is therefore essential to alter their ...

Parallax Barrier for Weakening Vernier Fringe in Naked-Eye LED 3D Display
International Journal of Optics, 2021 In naked-eye LED 3D display, vernier fringe is apparent for a conventional parallax barrier. This paper presents an intended misplaced parallax barrier with discrepant width of Light Translucent Slits (LTSs) to weaken vernier fringe.

Voltage-driven quantum oscillations in graphene [PDF]
, 2007 We predict unusual (for non-relativistic quantum mechanics) electron states in graphene, which are localized within a finite-width potential barrier. The density of localized states in the sufficiently high and/or wide graphene barrier exhibits a number ...

Vacuum decay and the transmission resonances in space-dependent electric fields [PDF]
, 2014 We investigate the decay of quantum electrodynamical (QED) vacuum in arbitrary space-dependent electric fields. In particular, we analyze the resonance peaks of the positron emission spectrum for the external fields with subcycle structure.

Effect of Landauer's blowtorch on the equilibration rate in a bistable potential [PDF]
, 1998 Kinetic aspect of Landauer's blowtorch effect is investigated for a model double-well potential with localized heating. Using the supersymmetric approach, we derive an approximate analytical expression for the equilibration rate as function of the ...

Electron tunnelling through a quantifiable barrier of variable width
Journal of Physics: Conference Series, 2009 This is the first study of electron tunnelling through a quantifiable barrier of adjustable width. We find quantitative agreement between the measured and calculated tunnelling probability with no adjustable constants. The tunnel barrier is a thin film of 3He on Cs1 which it wets.

Influence of Barrier Width on Spin-Polarisation Measured by Point Contact Andreev Reflection
, 2011 A modification of the Blonder–Tinkham–Klapwijk (BTK) model is proposed for the description of the ferromagnet-superconductor interface. Modelling the contact potential with a rectangular barrier, we investigate the influence of the barrier width at the ...
