Quantitatively understanding of angle-resolved polarized Raman scattering from black phosphorus

(Science China Press) Birefringence and linear dichroism in anisotropic materials would break down the selection rule for angle-resolved polarized Raman (ARPR) intensity. Recently, a research team led by Prof. Ping-Heng Tan from Institute of Semiconductors took black phosphorus as an example and proposed the birefringence-linear-dichroism model to quantitatively understand its ARPR intensity at normal and oblique laser incidences by the same set of real Raman tensors, where the birefringence and...
