BiOSe is a promising material for next-generation semiconducting electronics. It exhibits premature metallicity on the introduction of a tiny amount of electrons, the physi…
T-square resistivity without Umklapp scattering in dilute metallic BiOSe
Jialu Wang, Jing Wu, Tao Wang +7
The electrical resistivity of Fermi liquids (FLs) displays a quadratic temperature () dependence because of electron-electron (e-e) scattering. For such collisions to decay the…
Charge Transport in a Polar Metal
Jialu Wang, Liangwei Yang, Carl Willem Rischau +6
The fate of electric dipoles inside a Fermi sea is an old issue, yet poorly-explored. SrCaTiO hosts a robust but dilute ferroelectricity in a narrow ($0.002<x<0.0…
