Limitations of mean-field approximations in describing shift-current and injection-current in materials
Shunsuke A. Sato, Angel Rubio
We theoretically investigate bulk photovoltaic effects, with a specific focus on shift-current and injection-current. Initially, we perform a numerical analysis of the direct curre…
