The quantum phenomenon of shift photovoltaic current was predicted decades ago, but this effect never observed directly because and ballistic currents coexist. atomic-scale relaxation time shift, along with the absence a photo-Hall behavior, has made decisive measurement elusive. Here, we report facile, direct-current, steady-state method for unambiguous determination by means simultaneous measurements linear circular bulk under magnetic field, in sillenite piezoelectric crystal. Comparison...
Recently, it has been shown how shift and ballistic currents in piezoelectric sillenite crystals Bi$_{12}$GeO$_{20}$ Bi$_{12}$SiO$_{20}$ can be separated experimentally under the assumption that component of circular current is small. However, claimed cannot quantified by this method, due to magneto-photovoltaic effect caused either change crystal's spatial symmetry magnetic field or breaking time-reversal symmetry. Presently, we report observations photovoltaic Bi$_{12}$SiO$_{20}$, excited...
Abstract Ferroelectric materials, which exhibit switchable polarization, are potential candidates for photovoltaic applications owing to their intriguing charge carrier separation mechanism associated with polarization and breaking of inversion symmetry. To overcome the low photocurrent ferroelectrics, extensive efforts have focused on reducing bandgaps increase optical absorption solar spectrum thus power conversion efficiency. Here, a new avenue enhancing performance via engineering across...
