Phonon-mediated electron attraction in SrTiO via the generalized Fröhlich and deformation potential mechanisms
Christopher J. N. Coveney, Norm M. Tubman, Chih-En Hsu +6
Superconductivity in doped SrTiO was discovered in 1964, the first superconducting transition observed in a doped semiconductor. However, the mechanism of electron pairing in S…
Z topology and superconductivity from symmetry lowering of a 3D Dirac Metal AuPb
Leslie M. Schoop, Lilia S. Xie, Ru Chen +12
3D Dirac semi-metals (DSMs) are materials that have massless Dirac electrons and exhibit exotic physical properties It has been suggested that structurally distorting a DSM can cre…
Ytterbium-driven strong enhancement of electron-phonon coupling in graphene
Choongyu Hwang, Duck Young Kim, D. A. Siegel +7
We present high-resolution angle-resolved photoemission spectroscopy study in conjunction with first principles calculations to investigate how the interaction of electrons with ph…
On the possibility of superconductivity at higher temperatures in sp-valent diborides
J. B. Neaton, A. Perali
Superconducting transition temperatures ('s) of MgB, MgCaB, MgNaB, and MgAlB are studied within the McMillan approximation…
