Description:
Author(s): Benjamin M. Fregoso, Takahiro Morimoto, and Joel E. Moore A relationship is derived between differences in electric polarization between bands and the “shift vector” that controls part of a material's bulk photocurrent, then demonstrated in several models. Electric polarization has a quantized gauge ambiguity and is normally observed at surfaces via the su... [Phys. Rev. B 96, 075421] Published Wed Aug 16, 2017
