Berry curvature dipole generation and nonreciprocal spin photocurrents in ferroelectricity polarized heterostructures

Berry curvature dipole (BCD) describes the dipole-like distribution of Berry curvature in momentum space and plays a key role for quantum geometric phenomena in nonlinear optoelectronics. Experimentally, BCD can be generated at artificially designed semiconductor heterointerfaces...
