Alternate cleavage structure and electronic inhomogeneity in Ca-doped YBaCuO
Larissa B. Little, Jennifer Coulter, Ruizhe Kang +10
YBaCuO (YBCO) has favorable macroscopic superconducting properties of up to 93 K and up to 150 T. However, its nanoscale electronic structur…
Real-space visualization of quasiparticle dephasing near the Planckian limit in the Dirac line node material ZrSiS
Qingyu He, Lihui Zhou, Andreas W. Rost +4
Dirac line node (DLN) materials are topological semimetals wherein a set of symmetry protected crossing points forms a one-dimensional (1D) line in reciprocal space. Not only are t…
Acoustic plasmons and conducting carriers in hole-doped cuprate superconductors
A. Singh, H. Y. Huang, Christopher Lane +8
The superconductivity of cuprates, which has been a mystery ever since its discovery decades ago, is created through doping electrons or holes into a Mott insulator. There, however…
Monolayer FeSe on SrTiO
Dennis Huang, Jennifer E. Hoffman
Epitaxial engineering of solid-state heterointerfaces is a leading avenue to realizing enhanced or novel electronic states of matter. As a recent example, bulk FeSe is an unconvent…
Electric Field Tuning of Band Offsets in Transition Metal Dichalcogenides
Dennis Huang, Efthimios Kaxiras
We use first-principles calculations to investigate the band structure evolution of W/Mo ( = S, Se) heterobilayers under a perpendicular electric field. We characteriz…
Dumbbell Defects in FeSe Films: A Scanning Tunneling Microscopy and First-Principles Investigation
Dennis Huang, Tatiana A. Webb, Can-Li Song +4
The properties of iron-based superconductors (Fe-SCs) can be varied dramatically with the introduction of dopants and atomic defects. As a pressing example, FeSe, parent phase of t…
Bounds on Nanoscale Nematicity in Single-Layer FeSe/SrTiO
Dennis Huang, Tatiana A. Webb, Shiang Fang +5
We use scanning tunneling microscopy (STM) and quasiparticle interference (QPI) imaging to investigate the low-energy orbital texture of single-layer FeSe/SrTiO. We develop a $…
Revealing the Empty-State Electronic Structure of Single-Unit-Cell FeSe/SrTiO
Dennis Huang, Can-Li Song, Tatiana A. Webb +5
We use scanning tunneling spectroscopy to investigate the filled and empty electronic states of superconducting single-unit-cell FeSe deposited on SrTiO(001). We map the moment…
Nanoscale interplay of strain and doping in a high-temperature superconductor
Ilija Zeljkovic, Jouko Nieminen, Dennis Huang +10
The highest temperature superconductors are electronically inhomogeneous at the nanoscale, suggesting the existence of a local variable which could be harnessed to enhance the supe…
Etching of Cr tips for scanning tunneling microscopy of cleavable oxides
Dennis Huang, Stephen Liu, Ilija Zeljkovic +2
We report a detailed three-step roadmap for the fabrication and characterization of bulk Cr tips for spin-polarized scanning tunneling microscopy. Our strategy uniquely circumvents…
Nanoscale Surface Element Identification and Dopant Homogeneity in the High- Superconductor PrCaFeAs
Ilija Zeljkovic, Dennis Huang, Can-Li Song +3
We use scanning tunneling microscopy to determine the surface structure and dopant distribution in PrCaFeAs, the highest- member of the 122 family of iron-…
