Direct Fabrication of a Superconducting Two-Dimensional Electron Gas on KTaO3(111) via Mg-Induced Surface Reduction
Chun Sum Brian Pang, Bruce A. Davidson, Fengmiao Li +16
Two-dimensional electron gases (2DEGs) at the surfaces of KTaO3 have become an exciting platform for exploring strong spin-orbit coupling, Rashba physics, and low-carrier-density s…
Critical Role of Disorder for Superconductivity in the Series of Epitaxial Ti(O,N) Films
Fengmiao Li, Oliver Dicks, Myung-Geun Han +14
Realizing experimental control of superconductivity is of paramount importance to advancing both basic research and technological applications. Disorder, generally existing in most…
Ubiquitous suppression of the nodal coherent spectral weight in Bi-based cuprates
M. Zonno, F. Boschini, E. Razzoli +21
High-temperature superconducting cuprates exhibit an intriguing phenomenology for the low-energy elementary excitations. In particular, an unconventional temperature dependence of…
Sign inversion in the superconducting order parameter of LiFeAs inferred from Bogoliubov quasiparticle interference
Shun Chi, S. Johnston, G. Levy +10
Quasiparticle interference (QPI) by means of scanning tunneling microscopy/spectroscopy (STM/STS), angle resolved photoemission spectroscopy (ARPES), and multi-orbital tight bind-…
Observation of charge accumulation and onsite Coulomb repulsion at transition metal impurities in the iron pnictides
R. Kraus, V. Bisogni, L. Harnagea +7
We report a combined valence band photoemission and Auger spectroscopy study of single crystalline Ca(Fe,Co)2As2 and Ba(Fe,TM)2As2 with TM=Ni or Cu. The valence band photoemission…
Probing the role of Co substitution in the electronic structure of iron-pnictides
G. Levy, R. Sutarto, D. Chevrier +10
The role of Co substitution in the low-energy electronic structure of Ca(FeCo)As is investigated by resonant photoemission spectroscopy and density func…
Loss of nodal quasiparticle integrity in underdoped YBa2Cu3O6+x
D. Fournier, G. Levy, Y. Pennec +8
Arguably the most intriguing aspect of the physics of cuprates is the close proximity between the record high-Tc superconductivity (HTSC) and the antiferromagnetic charge-transfer…
