A depth resolved investigation of hydrogen uptake in carbon based nanostructures by soft-to-hard photoemission spectroscopy
Orlando Castellano, Alice Apponi, Luca Cecchini +11
Hydrogen chemisorption on graphitic carbon modifies the carbon orbital hybridization from sp2 to sp3, altering both structural and electronic properties. Understanding not only the…
Theory of Momentum-Resolved Electron Energy-Loss Spectra of Coupled Phonon and Magnon Excitations
José Ãngel Castellanos-Reyes, Ivan P. Miranda, Paul M. Zeiger +2
We develop a theory of momentum-resolved electron energy-loss spectra in the scanning transmission microscope (STEM-EELS) that captures the effects of coupled phonon and magnon exc…
Effects of Interactions and Defect Motion on Ramp Reversal Memory in Locally Phase Separated Materials
Y. Sun, M. Alzate Banguero, P. Salev +4
The ramp-reversal memory (RRM) effect in metal-insulator transition metal oxides (TMOs), a non-volatile resistance change induced by repeated temperature cycling, has attracted con…
Observation of Anomalous Hall Effect in Bulk Single Crystals of n-type Cr-doped SbTe Magnetic Topological Insulator
Ali Sarikhani, Mathew Pollard, Jacob Cook +7
The exploration of topological Dirac surface states is significant in the realms of condensed matter physics and future technological innovations. Among the materials garnering att…
