Spin-dependent anisotropic electron-phonon coupling in KTaO
Giulia Venditti, Francesco Macheda, Paolo Barone +2
KTaO (KTO) is an incipient ferroelectric, characterized by a softening of the lowest transverse optical (TO) mode with decreasing temperature. Cooper pairing in the recently di…
Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx
Jose Antonio Moreno, Mercè Roig, Víctor Barrena +14
Most superconducting materials exhibit a vanishing density of states at the Fermi level and Anderson's theorem posits that the superconducting gap is robust against nonmagnetic dis…
Large phonon-drag thermopower polarity reversal in Ba-doped KTaO3
Mohamed Nawwar, Samuel Poage, Tobias Schwaigert +6
This study reports the observation of phonon-drag thermopower polarity reversal in Ba-doped KTaO3 thin films, mediated by electron-phonon Umklapp scattering. Epitaxial films with d…
Layer-selective Cooper pairing in an alternately stacked transition metal dichalcogenide
Haojie Guo, Sandra Sajan, Irián Sánchez-Ramírez +9
Multigap superconductivity emerges when superconducting gaps form on distinct Fermi surfaces. Arising from locally overlapping atomic orbitals, multiple superconducting bands intro…
Violation of Pauli Limit at KTaO3(110) Interfaces
Samuel J. Poage, Xueshi Gao, Merve Baksi +7
The superconducting order parameter at the KTaO3 interfaces and its dependence on interface orientation remains a subject of debate. The superconductivity at these interfaces exhib…
