Z3 Charge Density Wave of Silicon Atomic Chains on a Vicinal Silicon Surface
Euihwan Do, Jae Whan Park, Oleksandr Stetsovych +2
An ideal one-dimensional electronic system is formed along atomic chains on Au-decorated vicinal silicon surfaces but the nature of its low temperature phases has been puzzled for…
Dual nature of localized phase defects in the In/Si(111) atomic wire array: impurities and short topological solitons
Abdus Samad Razzaq, Sun Kyu Song, Tae-Hwan Kim +2
We demonstrate the existence of atomically-sized topological solitons in a quasi one-dimensional charge density wave system: indium atomic wires on Si(111). Performing joint scanni…
Atomic structures and electronic correlation of monolayer 1T-TaSe2
Jae Whan Park, Han Woong Yeom
We investigate atomic and electronic structures of monolayer 1T-TaSe2 using density functional theory calculations. Monolayers of 1T-TaSe2 were recently grown on graphene substrate…
Tailoring high-TN interlayer antiferromagnetism in a van der Waals itinerant magnet
Junho Seo, Eun Su An, Taesu Park +12
Antiferromagnetic (AFM) van der Waals (vdW) materials provide a novel platform for synthetic AFM spintronics, in which the spin-related functionalities are derived from manipulatin…
Artificial Relativistic Molecules
Jae Whan Park, Hyo Sung Kim, Thomas Brumme +2
We fabricate artificial molecules composed of heavy atom lead on a van der Waals crystal. Pb atoms templated on a honeycomb charge-order superstructure of IrTe2 form clusters rangi…
Topological Landscape of Competing Charge Density Waves in 2H-NbSe2
Gyeongcheol Gye, Eunseok Oh, Han Woong Yeom
Despite decades of studies on charge density wave (CDW) of 2H-NbSe2, the origin of its incommensurate CDW ground state has not been understood. We discover that CDW of 2H-NbSe2 is…
