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…
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…
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…
Emergent Honeycomb Network of Topological Excitations in Correlated Charge Density Wave
Jae Whan Park, Gil Young Cho, Jinwon Lee +1
When two periodic potentials compete in materials, one may adopt the other, which straightforwardly generates topological defects. Of particular interest are domain walls in charge…
Stable Flatbands, Topology, and Superconductivity of Magic Honeycomb Networks
Jongjun M. Lee, Chenhua Geng, Jae Whan Park +4
We propose a new principle to realize flatbands which are robust in real materials, based on a network superstructure of one-dimensional segments. This mechanism is naturally reali…
