Abstract: Abstract We apply a bias to an electron-momentum filter constructed by patterning a ferromagnetic (FM) stripe and a Schottky metal (SM) stripe in a parallel configuration on surface of a GaAs/AlxGa1-xAs heterostructure, and theoretically explore… read more here.

Abstract: Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconductivity and charge-density wave order. A broad spectral phonon… read more here.

DOI: 10.1038/s41598-017-00628-4
Abstract: The relationship between electron momentum densities (EMDs) and a band gap is clarified in momentum space. The interference between wavefunctions via reciprocal lattice vectors, making a band gap in momentum space, causes the scattering of… read more here.
