Observation of metallic electronic structure in a single-atomic-layer oxide
Byungmin Sohn, Jeong Rae Kim, Choong H. Kim +11
Correlated electrons in transition metal oxides (TMOs) exhibit a variety of emergent phases. When TMOs are confined to a single-atomic-layer thickness, experiments so far have show…
Hund's metallicity enhanced by van Hove singularity in cubic perovskite systems
Hyeong Jun Lee, Choong H. Kim, Ara Go
A van Hove singularity (VHS) often significantly amplifies the electronic instability of a crystalline solid, including correlation-induced phenomena such as Hund's metallicity. We…
Observation of Kondo hybridization with an orbital-selective Mott phase in 4d Ca2-xSrxRuO4
Minsoo Kim, Junyoung Kwon, Choong H. Kim +12
The heavy fermion state with Kondo-hybridization (KH), usually manifested in f-electron systems with lanthanide or actinide elements, was recently discovered in several 3d transiti…
