Direct observation of the vanishing EELS cross section in graphene
Alberto Guandalini, Ryosuke Senga, Yung-Chang Lin +5
In transmission electron energy-loss spectroscopy, the cross section in 2D is quenched by kinematic effects once the momentum transfer becomes smaller than a critical value set by…
Temperature dependence of the Raman spectrum of orthorhombic Bi2Se3
Irene Mediavilla-Martinez, Christian Kramberger, Shabnam Dadgostar +9
Bismuth selenide, a benchmark topological insulator, grows in a trigonal structure at ambient conditions and exhibits a number of enticing properties related to the formation of Di…
Excitonic effects in energy loss spectra of freestanding graphene
Alberto Guandalini, Ryosuke Senga, Yung-Chang Lin +8
In this work we perform electron energy-loss spectroscopy (EELS) of freestanding graphene with high energy and momentum resolution to disentangle the quasielastic scattering from t…
/2 Mode Converters and Vortex Generators for Electrons
Christian Kramberger, Stefan Löffler, Thomas Schachinger +3
In optics, mode conversion is an elegant way to switch between Hermite Gaussian and Laguerre Gaussian beam profiles and thereby impart orbital angular momentum onto the beam and to…
Revealing the 3D Structure of Graphene Defects
Christoph Hofer, Christian Kramberger, Mohammad Reza Ahmadpour Monazam +5
We demonstrate insights into the three-dimensional structure of defects in graphene, in particular grain boundaries, obtained via a new approach from two transmission electron micr…
Incidence of multilayers in chemically exfoliated graphene
P. Szirmai, B. G. Márkus, J. C. Chacón-Torres +11
An efficient route to synthesize macroscopic amounts of graphene is highly desired and a bulk characterization of such samples, in terms of the number of layers, is equally importa…
