Steps on Rutile TiO2(110): Active Sites for Water and Methanol Dissociation
Umberto Martinez, Lasse B. Vilhelmsen, Henrik H. Kristoffersen +2
We present a detailed investigation of the structure and activity of extended defects namely monoatomic steps on (1x1)-TiO2(110). Specifically, the two most stable <001> and <1-11>…
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…
Electronic properties of the partially hydrogenated armchair carbon nanotubes
Željko Šljivančanin
By means of pseudopotential calculations based on density functional theory (DFT) we studied the effect of hydrogenation on electronic properties of armchair single-wall carbon nan…
Simultaneous quantization of bulk conduction and valence states through adsorption of nonmagnetic impurities on Bi2Se3
Marco Bianchi, Richard C. Hatch, Jianli Mi +2
Exposing the (111) surface of the topological insulator Bi2Se3 to carbon monoxide results in strong shifts of the features observed in angle-resolved photoemission. The behavior is…
Stability of the Bi2Se3(111) topological state: electron-phonon and -defect scattering
Richard C. Hatch, Marco Bianchi, Dandan Guan +6
The electron dynamics of the topological surface state on Bi2Se3(111) is investigated by temperature-dependent angle-resolved photoemission. The electron-phonon coupling strength i…
Large tuneable Rashba spin splitting of a two-dimensional electron gas in Bi2Se3
P. D. C. King, R. C. Hatch, M. Bianchi +18
We report a Rashba spin splitting of a two-dimensional electron gas in the topological insulator BiSe from angle-resolved photoemission spectroscopy. We further demonstrate…
