Spatial-Temporal Imaging of Anisotropic Photocarrier Dynamics in Black Phosphorus
Spatial-Temporal Imaging of Anisotropic Photocarrier Dynamics in Black Phosphorus
As an emerging single elemental layered material with a low symmetry in-plane crystal lattice, black phosphorus (BP) has attracted significant research interest owing to its unique electronic and optoelectronic properties, including its widely tunable bandgap, polarization-dependent photoresponse and highly anisotropic in-plane charge transport. Despite extensive study of the steady-state charge …
