Paper Abstract

The bulk photovoltaic effect describes the generation of photocurrents and photovoltages in bulk materials lacking a center of symmetry. Its principal mechanism is “shift current,” a nonlinear-optical, inherently quantum mechanical process. While most attention has been devoted to its prospects as a means of solar energy capture, shift current bulk photovoltaic effect possesses a number of distinguishing features that make it well-suited to sensing and switching applications: photovoltages substantially exceeding the material’s band gap, response amplitudes and directions that can depend on both photon energy and polarization, and response that occurs on ultrafast timescales.
