ARPES and XAS data of the Hsub2/subO (NHsub3/sub)/graphene/Ni(111) system give an information regarding the kind of interaction between the adsorbed molecules and the graphene on Ni(111). The presented experimental data are compared with the results obtained in the framework of the DFT ...

and J.P. carried out the ARPES studies. Q.L., L.K., H.S., P.D. and P.G. performed the calculations. M.Y., C.C., Y.S., M.C., F.R., L.K. and F. S. analysed and interpreted the results. M.Y., C.C., L.K. and F.R. wrote the manuscript. F.B. advised the...
such as molecular coronone, could be well reproduced from confined electrons in smooth and/or atomically corrugated quantum wells, where the spectral intensity as probed with angle resolved photoemission (ARPES) as well as the frontier orbitals coincides with DFT calculations24. In ...
The entire band-structure of a material can be determined by angle-resolved photoelectron spectroscopy (ARPES),35., 36., 37. while the work function of graphene and other materials is usually measured using a Kelvin probe.38 In a typical sensor-architecture the sensitive layer is contacted by ...

ARPESp-n junctionIntercalationWe propose a method to fabricate the chemical p-n junction in wafer-scale epitaxial graphene. In the case of Au intercalation in between graphene and SiC(0001), there exist two structurally distinct phases that result in p-type and n-type doping in the graphene ...
"Epitaxial graphene and exfoliated graphene are very distinct," said Li. Much of the synchrotron experimental work on epitaxial graphene has employed angle-resolved photoemission spectroscopy (ARPES). "In our work, we investigated exfoliated graphene by employing infrared spectromicroscopy." ...
1d. For clarity, we display the second derivative of the raw ARPES data. It can be seen that the equi-energy surface consists of two concentric triangularly warped contours that are centered around the K point corresponding to the two π bands of bilayer graphene. In Fig. 1e, we ...
Whereas techniques that are only sensitive to the low energy physics are often marred by impurities19,34, the ability of ARPES to access the entire energy range allows us to extract the intrinsic behavior of materials. Figure3d presents the energy dependence of the imaginary self-energy scaled by...
