Imaging and controlling plasmonic interference fields at buried interfaces

open access: yesNature Communications, 2016
Visualizing surface plasmon polaritons at buried interfaces has remained elusive. Here, the authors develop a methodology to study the spatiotemporal evolution of buried near-fields within complex heterostructures, enabling the characterization of the ...

Mapping the lattice dynamical anomaly of the order parameters across the Verwey transition in magnetite

open access: yesNew Journal of Physics, 2017
We present inelastic neutron scattering data across the Verwey transition in magnetite, obtained for a single crystal via a detwinning method. We provide direct evidence of the influence of the charge order on the transverse-acoustic phonons, associated ...

Electron Scattering in Boron Hexogonal Nitride

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2022
Investigation the effects of electron scattering in boron hexogonal nitride (h-BN) was performed. At present, material h-BN, together with graphene, is considered to be one of the most promising materials for the formation of new semiconductor devices ...

Electron-lattice and electron–electron interactions and Debye temperature studied by temperature dependence of secondary electron emission from insulators

open access: yesResults in Physics, 2020
The formulas for temperature dependence of λ(χreal, Eg, T), λ(χreal, Eg, T)p, ẟ and σ of insulators with less impurities were deduced and proved to be true; λ(χreal, Eg, T) is the mean escape depth of secondary electrons emitted from insulators with ...

Ultrafast structural and electronic dynamics of the metallic phase in a layered manganite

open access: yesStructural Dynamics, 2014
The transition between different states in manganites can be driven by various external stimuli. Controlling these transitions with light opens the possibility to investigate the microscopic path through which they evolve.

Electron scattering from tetrafluoroethylene

open access: yesThe Journal of Chemical Physics, 2004
We report experimental results for electron scattering from tetrafluoroethylene, C2F4, obtained from measurements in two laboratories. An extensive set of differential, integral, and momentum transfer cross sections is provided for elastic scattering for incident electron energies from 1 to 100 eV and inelastic (vibrational excitation) scattering for ...

Muon-electron scattering at NLO

open access: yesJournal of High Energy Physics, 2019
We consider the process of muon-electron elastic scattering, which has been proposed as an ideal framework to measure the running of the electromagnetic coupling constant at space-like momenta and determine the leading-order hadronic contribution to the ...
