Superconductivity-induced nematicity
Y. S. Kushnirenko, D. V. Evtushinsky, T. K. Kim +6
The role of nematic order for the mechanism of high-temperature superconductivity is highly debated. In most iron-based superconductors (IBS) the tetragonal symmetry is broken alre…
Hole-doping in BaFeAs: The case of BaNaFeAs single crystals
S. Aswartham, M. Abdel-Hafiez, D. Bombor +11
Single crystals of BaNaFeAs with = 0, 0.25, 0.35, 0.4 were grown using a self-flux high temperature solution growth technique. The superconducting and norma…
Evidence for conventional superconductivity in SrPd2Ge2
T. K. Kim, A. N. Yaresko, V. B. Zabolotnyy +12
Electronic structure of SrPd2Ge2 single crystals is studied by angle-resolved photoemission spectroscopy (ARPES), scanning tunneling spectroscopy (STS) and band-structure calculati…
Circular dichroism and bilayer splitting in the normal state of underdoped (Pb,Bi)Sr(CaY)CuO and overdoped (Pb,Bi)SrCaCuO
S. V. Borisenko, A. A. Kordyuk, S. Legner +11
We report an ARPES investigation of the circular dichroism in the first Brillouin zone (BZ) of under- and overdoped Pb-Bi2212 samples. We show that the dichroism has opposite signs…
Evidence for CuO conducting band splitting in the nodal direction of Bi-2212
A. A. Kordyuk, S. V. Borisenko, A. N. Yaresko +12
Using angle-resolved photoemission spectroscopy with ultimate momentum resolution we have explicitly resolved the bilayer splitting in the nodal direction of Bi-2212. The splitting…
Doping dependence of the many-body effects along the nodal direction in the high-Tc cuprate (Bi,Pb)_2Sr_2CaCu_2O_8
A. Koitzsch, S. V. Borisenko, A. A. Kordyuk +5
Angle-resolved photoemission spectroscopy (ARPES) is used to study the doping dependence of the lifetime and the mass renormalization of the low energy excitations in the high-Tc c…
Doping dependence of the mass enhancement in (Pb,Bi)_2 Sr_2 Ca Cu_2 O_8 at the antinodal point in the superconducting and normal state
T. K. Kim, A. A. Kordyuk, S. V. Borisenko +4
Angle-resolved photoemission spectroscopy (ARPES) is used to study the mass renormalization of the charge carriers in the high-T_c superconductor (Pb,Bi)_2Sr_2CaCu_2O_8 in the vici…
Superconducting gap in the presence of bilayer splitting in underdoped Bi(Pb)2212
S. V. Borisenko, A. A. Kordyuk, T. K. Kim +7
The clearly resolved bilayer splitting in ARPES spectra of the underdoped Pb-Bi2212 compound rises the question of how the bonding and antibonding sheets of the Fermi surface are g…
