Molecular fingerprints in the electronic properties of crystalline organic semiconductors: from experiment to theory
S. Ciuchi, R. C. Hatch, H. Höchst +3
By comparing photoemission spectroscopy with a non-perturbative dynamical mean field theory extension to many-body ab initio calculations, we show in the prominent case of pentacen…
Illuminating the dark corridor in graphene: polarization dependence of angle-resolved photoemission spectroscopy on graphene
Isabella Gierz, Juergen Henk, Hartmut Hoechst +2
We have used s- and p-polarized synchrotron radiation to image the electronic structure of epitaxial graphene near the K-point by angular resolved photoemission spectroscopy (ARPES…
Electron-phonon coupling in crystalline Pentacene films
Richard C. Hatch, David L. Huber, Hartmut Höchst
The electron-phonon(e-p) interaction in Pentacene (Pn) films grown on Bi(001) was investigated using photoemission spectroscopy. The spectra reveal thermal broadening from which we…
Experimental Electronic Structure and Interband Nesting in BaVS_3
S. Mitrovic, P. Fazekas, C. Sondergaard +9
The correlated 3d sulphide BaVS_3 is a most interesting compound because of the apparent coexistence of one-dimensional and three-dimensional properties. Our experiments explain th…
Photoemission view of electron fractionalization in quasi-one dimensional metal LiMoO
G. -H. Gweon, J. D. Denlinger, C. G. Olson +3
We report Luttinger liquid line shapes better revealed by new angle resolved photoemission data taken with a much improved angle resolution on a quasi-1-dimensional metal Li$_{0.9}…
ARPES Study of X-Point Band Overlaps in LaB and SmB - Contrast to SrB and EuB
S. -K. Mo, G. -H. Gweon, J. D. Denlinger +6
In contrast to our recent finding of an X-point band gap in divalent hexaborides, we report here that angle resolved photoemission spectroscopy (ARPES) data shows that the gap is a…
