“We were only able to obtain these new insights because BESSY II offers extremely sensitive instruments for measuring photoemission with spin resolution (Spin-ARPES). This leads to the fortunate situation that we can determine the assumed origin of the spin canting, i. e., the Rashba-type sp...
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 ...
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...
"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." ...
Moreover, ARPES and core-level photoemission results show that intercalation of Cu leads to significant electron injection into the nanoribbons, which causes a pronounced downshift of the valence and conduction bands of the GNR with respect to the Fermi energy (Delta E similar to 0.5 eV). As ...
High-resolution ARPES measurements are very useful for verifying the low-energy valence bands crossing the Fermi level along KΓ and MΓ and the rigid σ bands initiated from the Γ point. On the other hand, most of Si-substitution cases result in the semiconducting behavior with the finite ...
However, the coexistence of μm-sized grains of single and multilayer graphene with different azimuthal orientations and no rotational disorder within the grains was recently revealed for C-face graphene, but conventional ARPES still resolved only a single π-band. Here we report detailed nano-...
Here we present data on the electron-phonon interaction in highly-screened graphene, which we have analyzed by angle-resolved photoemission spectroscopy (ARPES). In contrast with every previous ARPES study, the magnitude of our extracted electron-phonon coupling constants generally agree with theoretical...
Previous ARPES studies on quasi-free-standing graphene grown on the C-face of SiC16 and H-terminated SiC17 have been conducted to achieve electronically decoupled graphene layers, but focused on SLG. Little is hence known, at present, about the spectral properties of the unperturbed, neutral ...
