Switchable photovoltaic and polarization modulated rectification in Si-integrated Pt/(Bi0.9Sm0.1)(Fe0.97Hf0.03)O3/LaNiO3 heterostructures
TL;DR: In this article, the Schottky barrier modulation by polarization flipping at Pt/BSFHO interface could be the main driving force behind switchable photovoltaic and rectifying diode characteristics of Pt/(Bi0.9Sm0.1)(Fe0.97Hf0.03)O3/ LaNiO3 (Pt/BFSFHO/LNO) heterostructures integrated on Si (100).

Modulation of oxygen vacancies assisted ferroelectric and photovoltaic properties of (Nd, V) co-doped BiFeO3 thin films
TL;DR: In this paper, the improved ferroelectric and photovoltaic properties of (Nd3+, V5+) co-doped (Bi0.95Nd0.05)(Fe1−x V x )O3 (BNFVO) (x = 0.01, 0.03) thin films were reported.
Long-range Stripe Nanodomains in Epitaxial (110) BiFeO 3 Thin Films on (100) NdGaO 3 Substrate
Yogesh Sharma,Radhe Agarwal,Charudatta Phatak,Bumsoo Kim,Bumsoo Kim,Seokwoo Jeon,Ram S. Katiyar,Seungbum Hong,Seungbum Hong +8 more
TL;DR: Long range ordering of ferroelectric 109° stripe nanodomains separated by periodic vertical domain walls in as-grown 130 nm thick BFO films can be useful for optoelectronic devices and ferroelastic templates for strain coupled artificial magnetoelectric heterostructures.
Shift photovoltaic current and magnetically induced bulk photocurrent in piezoelectric sillenite crystals
Aaron M. Burger,Lingyuan Gao,Radhe Agarwal,Alexey Aprelev,Jonathan E. Spanier,Andrew M. Rappe,Vladimir M. Fridkin +6 more
TL;DR: In this article, it was shown that the magnetophotovoltaic current constitutes a significant fraction of the measured current in the Hall direction for piezoelectric sillenite crystals under specific experimental conditions.
