Abstract

Ultrafast photocurrent spectroscopy is used to investigate the carrier lifetime of a black phosphorus heterostructure. Tuning the polarization reveals anisotropic response of the excitons with the optical field. Individual ultrafast pulses with a spacing of ~1ns are resolved with our device.
