Origin of sublattice particle-hole asymmetry in monolayer FeSe superconductors
Mercè Roig, Kazi Ranjibul Islam, Basu Dev Oli +7
In iron-based superconductors, the two Fe atoms in the unit cell are typically related by crystal symmetries; therefore, we expect no intra-unit cell variations in the superconduct…
Symmetry-required Orbital Selectivity in Monolayer FeSe
Mercè Roig, Qiang Zou, Basu Dev Oli +6
Orbital-selective correlations have been observed to play an important role in Fe-based superconductors. Here, in contrast to previous site-local Mott transition-based origins, we…
Correlation Enhanced Electron-Phonon Coupling in FeSe/SrTiO at a Magic Angle
Qiang Zou, Antik Sihi, Basu Dev Oli +5
While a predictive theory for unconventional superconductivity in Fe-based superconductors remains elusive, an extensively debated aspect is the interaction between phonons and str…
Light-driven lattice metastability for enhanced superconductivity in FeSe/SrTiO3
Qiang Zou, Zhan Su, Andres Tellez Mora +11
Driven quantum materials with on demand properties controlled by external stimuli are critical for emergent quantum technology. In optically tunable superconducting heterostructure…
Anisotropic response of defect bound states to magnetic field in epitaxial FeSn films
Huimin Zhang, Zhengfei Wang, Michael Weinert +1
Crystal defects, whether intrinsic or engineered, drive many fundamental phenomena and novel functionalities of quantum materials. Here, we report symmetry-breaking phenomena induc…
Unraveling Enhanced Superconductivity in Single-layer FeSe through Substrate Surface Terminations
Qiang Zou, Gi-Yeop Kim, Jong-Hoon Kang +7
Single-layer FeSe films grown on (001) SrTiO3 substrates have shown a significant increase in superconducting transition temperature compared to bulk FeSe. Several mechanisms have…
KPROJ: A Program for Unfolding Electronic and Phononic Bands
Jiaxin Chen, M. Weinert, Mingxing Chen
We introduce a program named KPROJ that unfolds the electronic and phononic band structure of materials modeled by supercells. The program is based on the -projection m…
Effects of interface oxygen vacancies on electronic bands of FeSe/SrTiO3(001)
M. X. Chen, Zhuozhi Ge, Y. Y. Li +3
Modifications of the electronic bands of thin FeSe films due to oxygen vacancies in the supporting SrTiO 3 (001) substrate - and the interplay with spin-orbit coupling, magnetism,…
Half-metallic Dirac cone in zigzag-graphene-nanoribbon/graphene
M. X. Chen, M. Weinert
The Dirac electrons of graphene, an intrinsic zero gap semiconductor, uniquely carry spin and pseudospin that give rise to many fascinating electronic and transport properties. Whi…
Epitaxial graphene on SiC(0001): More than just honeycombs
Y. Qi, S. H. Rhim, G. F. Sun +2
The potential of graphene to impact the development of the next generation of electronics has renewed interest in its growth and structure. The graphitization of hexagonal SiC surf…
