Floquet spintronics: tuning the current-induced spin polarization of topological surface states with light
Youngjae Kim, Aayushi Agrawal, Kwon Park
Topological surface states are a promising platform for spintronics due to spin-momentum locking. Spin-momentum locking can induce a net spin polarization in topological surface st…

High Photovoltaic Efficiency in Bulk-Stacked One-Dimensional GeSe van der Waals Crystal
Seoung-Hun Kang, Youngjae Kim, Bo Gyu Jang +1
Germanium diselenide (GeSe) has recently attracted substantial interest as a rare example of one-dimensional (1D) van der Waals material. Here, we investigate the photovoltai…
