摘要：

High-aspect-ratio single-crystalline KNN nanorods (length similar to 10-20 mu m and diameter similar to 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 similar to 230 pm V-1 may be used in biosensing and energy-harvesting micro-devices.
