Surface reconstruction and charge modulation in BaFe2As2 superconducting film
S. Kim, S. Yi, M. Oh +13
Whether or not epitaxially grown superconducting films have the same bulk-like superconducting properties is an important concern. We report the structure and the electronic proper…
Selective resolution of phonon modes in STM-IETS on clean and oxygen-adsorbed Cu(100) surfaces
Minjun Lee, Myungchul Oh, Hoyeon Jeon +5
The observation of surface phonon dispersion using local probes can provide important information related to local structural and thermal properties. In this study, surface phonon…
Strain Engineering a Charge Density Wave Phase in Transition Metal Dichalcogenide 1T-VSe
Duming Zhang, Jeonghoon Ha, Hongwoo Baek +10
We report a rectangular charge density wave (CDW) phase in strained 1T-VSe thin films synthesized by molecular beam epitaxy on c-sapphire substrates. The observed CDW structure…
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…
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…
Scanning Tunneling Spectroscopy of Proximity Superconductivity in Epitaxial Multilayer Graphene
Fabian D. Natterer, Jeonghoon Ha, Hongwoo Baek +5
We report on spatial measurements of the superconducting proximity effect in epitaxial graphene induced by a graphene-superconductor interface. Superconducting aluminum films were…
