Spin-flip reflection of electrons from a potential barrier in heterostructures [PDF]

open access: yes, 2014
Spin-conserving and spin-flip opaque reflections of electrons from a potential barrier in heterostructures are described. An electric field of the barrier is considered to be the only source of energy spin splitting in the presence of spin-orbit ...

Wideband tunable perfect absorption of graphene plasmons via attenuated total reflection in Otto prism configuration

open access: yesNanophotonics, 2020
A strategy is proposed to achieve wideband tunable perfect plasmonic absorption in graphene nanoribbons by employing attenuated total refraction (ATR) in Otto prism configuration. In this configuration, the Otto prism with a deep-subwavelength dielectric

Infrared spectroscopy using attenuated total reflection

open access: yesJournal of Pharmacy and Pharmacology, 1974
Abstract An ATR method is given for the examination of pharmaceuticals in the solid state as a layer of crystals on adhesive tape. Representative spectra are chosen to compare with, and to indicate advantages over, disc and mull techniques.
