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…
Percolative Pathway to Stripe Order in KTaO3-Based Superconductivity
Zhihao Chen, Chun Sum Brian Pang, Meng Yang +8
The sensitivity of low dimensional superconductors to fluctuations gives rise to emergent behaviors beyond the conventional Bardeen Cooper Schrieffer framework. Anisotropy is one 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…
The Three-Dimensional Electronic Structure of LiFeAs: Strong-coupling Superconductivity and Topology in the Iron Pnictides
Ryan P. Day, MengXing Na, Manuel Zingl +15
Amongst the iron-based superconductors, LiFeAs is unrivalled in the simplicity of its crystal structure and phase diagram. However, our understanding of this canonical compound suf…
Effect of Pt substitution on the electronic structure of AuTe2
D. Ootsuki, K. Takubo, K. Kudo +12
We report a photoemission and x-ray absorption study on Au1-xPtxTe2 (x = 0 and 0.35) triangular lattice in which superconductivity is induced by Pt substitution for Au. Au 4f and T…
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-…

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…
Surface-enhanced charge-density-wave instability in underdoped Bi2201
J. A. Rosen, R. Comin, G. Levy +20
Neutron and x-ray scattering experiments have provided mounting evidence for spin and charge ordering phenomena in underdoped cuprates. These range from early work on stripe correl…
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…
Controlling the self-doping of YBa2C3O7-d polar surfaces: From Fermi surface to nodal Fermi arcs by ARPES
M. A. Hossain, J. D. F. Mottershead, A. Bostwick +8
The discovery of quantum oscillations in the normal-state electrical resistivity of YBa2Cu3O6.5 provides the first evidence for the existence of Fermi surface (FS) pockets in an un…
