Ultraviolet optical conductivity, exciton fine-structure and dispersion of freestanding monolayer h-BN
Jinhua Hong, Alberto Guandalini, Weibin Wu +7
Excitons govern the light-matter interaction in 2D gapped materials with intrinsically large binding energies. In spite of plentiful optical measurements in the visible for semicon…
Core-hole induced misalignment between Van-Hove singularities and K-edge fine structure in carbon nanotubes
Martin Unzog, Alexey Tal, Pedro Melo +4
We investigate the relationship between the K-edge fine structure of isolated single-wall carbon nanotubes (SWCNTs) and the Van Hove singularities (VHSs) in the conduction band den…
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…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
Electron-electron correlation in graphite
A. Gruneis, C. Attaccalite, T. Pichler +12
The full three dimensional dispersion of the pi-bands, Fermi velocities and effective masses are measured with angle resolved photoemission spectroscopy and compared to first-princ…
The joys and pitfalls of Fermi surface mapping in Bi2212 using angle resolved photoemission
S. V. Borisenko, M. S. Golden, S. Legner +7
On the basis of angle-scanned photoemission data recorded using unpolarised radiation, with high (E,k) resolution, and an extremely dense sampling of k-space, we resolve the curren…
The size of electron-hole pairs in pi conjugated systems
M. Knupfer, T. Pichler, M. S. Golden +5
We have performed momentum dependent electron energy-loss studies of the electronic excitations in sexithiophene and compared the results to those from parent oligomers. Our experi…
