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…
Layer controlled orbital selective Mott transition in monolayer nickelate
Byungmin Sohn, Minjae Kim, Sangjae Lee +14
Dimensionality and electronic correlations are crucial elements of many quantum material properties. An example is the change of the electronic structure accompanied by the loss of…
Magnetic Ni-N-Ni Centers in N-substituted NiO
Simon Godin, Ilya S. Elfimov, Fengmiao Li +6
To explore how anion substitution modifies the existing magnetism in strongly correlated oxides, we investigate local electronic states and magnetic ordering in nickel oxide (NiO)…
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…
