Momentum-resolved electronic structure at a buried interface from soft x-ray standing-wave angle-resolved photoemission
A. X. Gray, J. Minár, L. Plucinski +19
Angle-resolved photoemission spectroscopy (ARPES) is a powerful technique for the study of electronic structure, but it lacks a direct ability to study buried interfaces between tw…
Tunable polaronic conduction in anatase TiO2
S. Moser, L. Moreschini, J. Jacimovic +9
Oxygen vacancies created in anatase TiO2 by UV photons (80 - 130 eV) provide an effective electron-doping mechanism and induce a hitherto unobserved dispersive metallic state. Angl…
Visualizing Atomic-Scale Negative Differential Resistance in Bilayer Graphene
Keun Su Kim, Tae-Hwan Kim, Andrew L. Walter +4
We investigate the atomic-scale tunneling characteristics of bilayer graphene on silicon carbide using the scanning tunneling microscopy. The high-resolution tunneling spectroscopy…
