Metal-insulator transition of the reduced surface of yttria-stabilized zirconia near Pt electrodes
D. A. Siegel, F. El Gabaly, K. F. McCarty +1
The electrochemical reactions of solid oxide fuel cells occur in the region where gas-phase species, electrode, and electrolyte coincide. When the electrode is an ionic insulator a…
In-plane orientation effects on the electronic structure, stability and Raman scattering of monolayer graphene on Ir(111)
Elena Starodub, Aaron Bostwick, Luca Moreschini +4
We employ angle-resolved photoemission spectroscopy (ARPES) to investigate the electronic structures of two rotational variants of epitaxial, single-layer graphene on Ir(111). As g…
A high-efficiency spin-resolved phototemission spectrometer combining time-of-flight spectroscopy with exchange-scattering polarimetry
C. Jozwiak, J. Graf, G. Lebedev +7
We describe a spin-resolved electron spectrometer capable of uniquely efficient and high energy resolution measurements. Spin analysis is obtained through polarimetry based on low-…
Measuring individual overpotentials in an operating solid-oxide electrochemical cell
Farid El Gabaly, Michael Grass, Anthony H. McDaniel +6
We use photo-electrons as a non-contact probe to measure local electrical potentials in a solid-oxide electrochemical cell. We characterize the cell in operando at near-ambient pre…
Real-Time Observation of Reactive Spreading of Gold on Silicon
Nicola Ferralis, Farid El Gabaly, Andreas K. Schmid +2
The spreading of a bilayer gold film propagating outward from gold clusters, which are pinned to clean Si(111), is imaged in real time by low energy electron microscopy. By monitor…
Morphology of graphene thin film growth on SiC(0001)
Taisuke Ohta, Farid El Gabaly, Aaron Bostwick +6
Epitaxial films of graphene on SiC(0001) are interesting from a basic physics as well as applications-oriented point of view. Here we study the emerging morphology of in-vacuo prep…
