Abstract
High-aspect-ratio single-crystalline KNN nanorods (length ∼10-20 μm and diameter ∼400 nm) are synthesized using a facile method based on a molten-salt reaction, whose formation mechanism has been revealed. The lead-free piezoelectric nanorods showing high piezoelectric coefficient d*33 up to ∼230 pm V(-1) may be used in bio-sensing and energy-harvesting micro-devices.
