Popis: We demonstrate an efficient optoelectronic platform using WSe2/hBN/Bi2Se3 van der Waals heterostructures to manipulate the photocarrier polarization and dynamics. Our observations are corroborated by the comprehensive polarization, external electric field, and two-pulse delay dependence behaviors.
