Epitaxial patterned BiFeCrO nanoisland arrays with room temperature multiferroic properties.

Epitaxial multiferroic BiFeCrO nanoisland arrays with a lateral size of ∼100 nm have been successfully fabricated by patterned SiO template-assisted pulsed laser deposition. The as-grown island structure exhibits promising multiferroic properties ( ferroelectric and magnetic) even at nanometer dimensions at room temperature. This work demonstrates an effective strategy to fabricate high-density nonvolatile ferroelectric/multiferroic memory devices.

Highly Efficient and Ultrasensitive Large-Area Flexible Photodetector Based on Perovskite Nanowires.

Hybrid organic-inorganic perovskites have shown exceptional semiconducting properties and microstructural versatility for inexpensive, solution-processable photovoltaic and optoelectronic devices. In this work, an all-solution-based technique in ambient environment for highly sensitive and high-speed flexible photodetectors using high crystal quality perovskite nanowires grown on Kapton substrate is presented. At 10 V, the optimized photodetector exhibits a responsivity as high as 0.
