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…
Correlated electronic states at domain walls of a Mott-charge-density-wave insulator 1T-TaS2
Doohee Cho, Gyeongcheol Gye, Jinwon Lee +4
Domain walls in interacting electronic systems can have distinct localized states, which often govern physical properties and may lead to unprecedented functionalities and novel de…
Switching Chiral Solitons for Algebraic Operation of Topological Quaternary Digits
Tae-Hwan Kim, Sangmo Cheon, Han Woong Yeom
Chirality is ubiquitous in nature and chiral objects in condensed matter are often excited states protected by system's topology. The use of chiral topological excitations to carry…
Topological phase transition and quantum spin Hall edge states of antimony few layers
Sung Hwan Kim, Kyung-Hwan Jin, Joonbum Park +3
While two-dimensional topological insulators (2D TI) initiated the field of topological materials, only very few materials were discovered to date and the direct access to their qu…
Topological Solitons versus Non-Solitonic Phase Defects in Quasi-One-Dimensional Charge Density Wave
Tae-Hwan Kim, Han Woong Yeom
We investigated phase defects in a quasi-one-dimensional commensurate charge density wave (CDW) system, an In atomic wire array on Si(111), using low temperature scanning tunneling…
