Intrinsic magnetic topological insulators have emerged as a promising platform to study the interplay between topological surface states and ferromagnetism. This unique interplay c…
Layer-by-layer disentanglement of Bloch states via frequency-domain photoemission
Woojoo Lee, Sebastian Fernandez-Mulligan, Hengxin Tan +8
Layer-by-layer material engineering has enabled exotic quantum phenomena such as interfacial superconductivity and the quantum anomalous Hall effect. Meanwhile, deciphering electro…
Exciton-Driven Renormalization of Quasiparticle Band Structure in Monolayer MoS2
Yi Lin, Yang-hao Chan, Woojoo Lee +7
Optical excitation serves as a powerful approach to control the electronic structure of layered Van der Waals materials via many-body screening effects, induced by photoexcited fre…
Confined monolayer Ag as a large gap 2D semiconductor and its momentum resolved excited states
Woojoo Lee, Yuanxi Wang, Wei Qin +11
2D materials have intriguing quantum phenomena that are distinctively different from their bulk counterparts. Recently, epitaxially synthesized wafer-scale 2D metals, composed of e…
Critical role of parallel momentum in quantum well state couplings in multi-stacked nanofilms: an angle resolved photoemission study
Woojoo Lee, Chi-Ruei Pan, Hyoungdo Nam +2
We use angle resolved photoemission spectroscopy (ARPES) to investigate the coupling of electron quantum well states (QWS) in epitaxial thin Pb and Ag films. More specifically, we…
Momentum resolved ground/excited states and the ultra-fast excited state dynamics of monolayer MoS2
