Imaging of van der Waals Materials via Standing-Wave Photoemission Microscopy: Depth-Resolved Electronic Structure of WS2
J. R. Paudel, R. Muzzio, M. E. Matzelle +13
Two-dimensional van der Waals materials promise electronic, optoelectronic, and quantum technologies, yet depth-resolved characterization remains challenging. Here, we demonstrate…
Rotational Phonons Drive Low-Energy Kinks in Cuprate Superconductors
Yanyong Wang, Manuel Engel, Christopher Lane +9
Angle-resolved photoemission spectroscopy (ARPES) reveals ubiquitous quasiparticle ``kinks'' near 70 meV and 40 meV across cuprate superconductors, often accompanied by…
Investigating the Electronic and Magnetic Properties of NaFeMnO Cathode Materials with X-ray Compton Scattering
Veenavee Nipunika Kothalawala, Kosuke Suzuki, Johannes Nokelainen +21
We discuss electronic and magnetic properties of NaFeMnO, a promising Na-ion battery cathode material. Using x-ray Compton scattering, SQUID magnetometry, a…
Probing the semiconductor-to-dirac semimetal transition in Na-Sb-Bi alloys with x-ray Compton scattering
Aki Pulkkinen, Veenavee Nipunika Kothalawala, Kosuke Suzuki +12
We discuss electron redistribution during the semiconductor-to-Dirac semimetal transition in Na-Sb-Bi alloys using x-ray Compton scattering experiments combined with first-principl…
Accurate Electron-phonon Interactions from Advanced Density Functional Theory
Yanyong Wang, Manuel Engel, Christopher Lane +9
Electron-phonon coupling (EPC) is key for understanding many properties of materials such as superconductivity and electric resistivity. Although first principles density-functiona…
