Correlation between electronic polarization and shift current in cubic and hexagonal semiconductors LiZn$X$ ($X$ = P, As, Sb)

Urmimala Dey, Jeroen van den Brink, Rajyavardhan Ray

The rectified bulk photovoltaic effect (BPVE) in noncentrosymmetric semiconductors, also called shift current, is considered promising for optoelectronic devices, terahertz emissio…
