Quantum confinement effects in Pb Nanocrystals grown on InAs
Tianzhen Zhang, Sergio Vlaic, Stéphane Pons +9
In the recent work of Ref.\cite{Vlaic2017-bs}, it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Cou…
Spin-Orbit induced phase-shift in BiSe Josephson junctions
Alexandre Assouline, Cheryl Feuillet-Palma, Nicolas Bergeal +8
The transmission of Cooper pairs between two weakly coupled superconductors produces a superfluid current and a phase difference; the celebrated Josephson effect. Because of time-r…
Shiba Bound States across the mobility edge in doped InAs nanowires
Alexandre Assouline, Cheryl Feuillet-Palma, Alexandre Zimmers +3
We present a study of Andreev Quantum Dots (QDots) fabricated with small-diameter (30 nm) Si-doped InAs nanowires where the Fermi level can be tuned across a mobility edge separati…
Superconducting parity effect across the Anderson limit
Sergio Vlaic, Stéphane Pons, Tianzhen Zhang +7
How small superconductors can be? For isolated nanoparticles subject to quantum size effects, P.W. Anderson conjectured in 1959 that superconductivity could only exist when the ele…
Anisotropic dressing of charge-carriers in the electron-doped cuprate superconductor Sm(1.85)Ce(0.15)CuO(4) from angle-resolved photoemission measurements
A. F. Santander-Syro, T. Kondo, J. Chang +8
Angle-resolved photoemission measurements on the electron-doped cuprate Sm(1.85)Ce(0.15)CuO(4) evidence anisotropic dressing of charge-carriers due to many-body interactions. Most…
Local tunneling spectroscopy of the electron-doped cuprate Sm1.85Ce0.15CuO4
A. Zimmers, Y. Noat, T. Cren +4
We present local tunneling spectroscopy in the optimally electron-doped cuprate Sm2-xCexCuO4 x=0.15. A clear signature of the superconducting gap is observed with an amplitude rang…
Optical determination of the superconducting energy gap in electron-doped Pr_{1.85}Ce_{0.15}CuO_4
C. C. Homes, R. P. S. M. Lobo, P. Fournier +2
The optical properties of single crystal Pr_{1.85}Ce_{0.15}CuO_4 have been measured over a wide frequency range above and below the critical temperature (T_c \simeq 20 K). In the n…
Temperature dependence of the spectral weight in p- and n-type cuprates: a study of normal state partial gaps and electronic kinetic energy
N. Bontemps, R. P. S. M. Lobo, A. F. Santander-Syro +1
The optical conductivity of CuO2 (copper-oxygen) planes in p- and n-type cuprates thin films at various doping levels is deduced from highly accurate reflectivity data. The tempera…

A. Zimmers, L. Shi, D. C. Schmadel +10
The electron-doped cuprate Pr(2-x)Ce(x)CuO(4) is investigated using infrared magneto-optical measurements. The optical Hall conductivity sigma_{xy} shows a strong doping, frequency…
Infrared Properties of Electron Doped Cuprates: Tracking Normal State Gaps and Quantum Critical Behavior in Pr(2-x)Ce(x)CuO(4)
A. Zimmers, J. M. Tomczak, R. P. S. M. Lobo +7
We report the temperature dependence of the infrared-visible conductivity of Pr(2-x)Ce(x)CuO(4) thin films. When varying the doping from a non-superconducting film (x = 0.11) to a…
Infrared Signature of the Superconducting State in Pr(2-x)Ce(x)CuO(4)
A. Zimmers, R. P. S. M. Lobo, N. Bontemps +4
We measured the far infrared reflectivity of two superconducting Pr(2-x)Ce(x)CuO(4) films above and below Tc. The reflectivity in the superconducting state increases and the optica…
