Using -means to sort spectra: electronic order mapping from scanning tunneling spectroscopy measurements
V. King, Seokhwan Choi, Dong Chen +7
Hyperspectral imaging techniques have a unique ability to probe the inhomogeneity of material properties whether driven by compositional variation or other forms of phase segregati…
Quasiparticle interference observation of the topologically non-trivial drumhead surface state in ZrSiTe
B. A. Stuart, Seokhwan Choi, Jisun Kim +6
Drumhead surface states that link together loops of nodal lines arise in Dirac nodal-line semimetals as a consequence of the topologically non-trivial band crossings. We used low-t…
Versatile Variable Temperature and Magnetic Field Scanning Probe Microscope for Advanced Material Research
Jin-Oh Jung, Seokhwan Choi, Yeonghoon Lee +3
We have built a variable temperature scanning probe microscope (SPM) that covers 4.6 K - 180 K and up to 7 Tesla whose SPM head fits in a 52 mm bore magnet. It features a temperatu…
Switching Magnetism and Superconductivity with Spin-Polarized Current in Iron-Based Superconductor
Seokhwan Choi, Hyoung Joon Choi, Jong Mok Ok +11
We have explored a new mechanism for switching magnetism and superconductivity in a magnetically frustrated iron-based superconductor using spin-polarized scanning tunneling micros…
Correlation of Fe-based Superconductivity and Electron-Phonon Coupling in an FeAs/Oxide Heterostructure
Seokhwan Choi, Steven Johnston, Won-Jun Jang +11
Interfacial phonons between iron-based superconductors (FeSCs) and perovskite substrates have received considerable attention due to the possibility of enhancing preexisting superc…
Atomic-scale observation and manipulation of plaquette antiferromagnetic order in iron-based superconductor
Seokhwan Choi, Won-Jun Jang, Jong Mok Ok +10
The symmetry requirement and the origin of magnetic orders coexisting with superconductivity have been strongly debated issues of iron-based superconductors (FeSCs). Observation of…
