Gate-imprinted memory and light-induced erasure of superconductivity at KTaO-based interfaces
Zhihao Chen, Pengxu Ran, Ming Dong Dong +7
Realizing non-volatile control of superconductivity is a key step toward integrating memory and quantum functionality in future information technologies. KTaO-based heterostruc…
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…
Modulation doping of the FeSe monolayer on SrTiO
Fengmiao Li, Ilya Elfimov, George A. Sawatzky
The discovery of higher-temperature superconductivity in FeSe monolayers on SrTiO (STO) substrates has sparked a surge of interest in the interface superconductivity. One point…
Controlling the electrical and magnetic ground states by doping in the complete phase diagram of titanate Eu1-xLaxTiO3 thin films
Hyungki Shin, Chong Liu, Fengmiao Li +3
EuTiO3, a band insulator, and LaTiO3, a Mott insulator, are both antiferromagnetic with transition temperatures ~ 5.5 K and ~ 160 K, respectively. Here, we report the synthesis of…
Epitaxial Growth of Perovskite SrBiO Film on SrTiO by Oxide Molecular Beam Epitaxy
Fengmiao Li, Bruce A. Davidson, Ronny Sutarto +7
Hole-doped perovskite bismuthates such as BaKBiO and SrKBiO are well-known bismuth-based oxide high-transition-temperature superconductors. Reported…
Strain-induced Defect Superstructure on the SrTiO3(110) Surface
Zhiming Wang, Fengmiao Li, Sheng Meng +4
We report on a combined scanning tunneling microscopy and density functional theory calculation study of the SrTiO3(110)-(4 x 1) surface. It is found that antiphase domains are for…
Electron phonon coupling versus photoelectron energy loss at the origin of replica bands in photoemission of FeSe on SrTiO
Fengmiao Li, George A. Sawatzky
The recent observation of replica bands in single-layer FeSe/SrTiO by angle-resolved photoemission spectroscopy (ARPES) has triggered intense discussions concerning the potenti…
Reversible Transition Between Thermodynamically Stable Phases with Low Density of Oxygen Vacancies on SrTiO(110) Surface
Fengmiao Li, Zhiming Wang, Sheng Meng +4
The surface reconstruction of SrTiO(110) is studied with scanning tunneling microscopy and density functional theory (DFT) calculations. The reversible phase transition between…
