An electronic band sculpted by oxygen vacancies and indispensable for dilute superconductivity
Benoît Fauqué, Clément Collignon, Hyeok Yoon +5
Dilute superconductivity survives in bulk strontium titanate when the Fermi temperature falls well below the Debye temperature. Here, we show that the onset of the superconducting…
Thermopower across the phase diagram of the cuprate LaNdSrCuO : signatures of the pseudogap and charge-density-wave phases
C. Collignon, A. Ataei, A. Gourgout +11
The Seebeck coefficient (thermopower) of the cuprate superconductor LaNdSrCuO was measured across its doping phase diagram (from to $p = 0.…
Wiedemann-Franz law and abrupt change in conductivity across the pseudogap critical point of a cuprate superconductor
B. Michon, A. Ataei, P. Bourgeois-Hope +8
The thermal conductivity of the cuprate superconductor LaNdSrCuO was measured down to 50 mK in seven crystals with doping from to , b…
Metallicity and superconductivity in doped strontium titanate
Clément Collignon, Xiao Lin, Carl Willem Rischau +2
Strontium titanate is a wide-gap semiconductor avoiding a ferroelectric instability thanks to quantum fluctuations. This proximity leads to strong screening of static Coulomb inter…
Pseudogap phase of cuprate superconductors confined by Fermi surface topology
N. Doiron-Leyraud, O. Cyr-Choinière, S. Badoux +15
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which…
Pseudogap temperature of cuprate superconductors from the Nernst effect
O. Cyr-Choinière, R. Daou, F. Laliberté +17
We use the Nernst effect to delineate the boundary of the pseudogap phase in the temperature-doping phase diagram of cuprate superconductors. New data for the Nernst coefficient $ν…
