Atomically Abrupt Topological p-n Junction
Sung Hwan Kim, Kyung-Hwan Jin, Byung Woo Kho +4
Topological insulators (TI's) are a new class of quantum matter with extraordinary surface electronic states, which bear great potential for spintronics and error-tolerant quantum…
Temperature-dependent evolutions of excitonic superfluid plasma frequency in a srong excitonic insulator candidate, TaNiSe
Yu-Seong Seo, Man Jin Eom, Jun Sung Kim +3
We investigate an interesting anisotropic van der Waals material, TaNiSe, using optical spectroscopy. TaNiSe has been known as one of the few excitonic insu…
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…
Frustration-driven C4 symmetric orders in a hetero-structured iron-based superconductor
Jong Mok Ok, S. -H. Baek, C. Hoch +11
A subtle balance between competing interactions in strongly correlated systems can be easily tipped by additional interfacial interactions in a heterostructure. This often induces…
