Pure bulk orbital and spin photocurrent in two-dimensional ferroelectric materials
X. Mu, Y. Pan, et al.
Discover groundbreaking research by Xingchi Mu, Yiming Pan, and Jian Zhou, revealing a bias-free light-induced orbital and spin current in centrosymmetric broken materials. This study extends the bulk photovoltaic effect, demonstrating a pure orbital moment current that transforms into a pure spin current, all while proposing a novel four-terminal device for measurement.
