Piezoelectric properties of rhombic LiNbO3 nanowires

Rhombic LiNbO3 nanowires along the c-axis were synthesized by using wire-like NH4Nb3O8 as the starting material based on a molten salt reaction with Li2CO3 powders in the KCl melt. Meanwhile, the as-synthesized LiNbO3 nanowires exhibit excellent piezoactivity. An effective piezoelectric coefficient of around 100 pm V-1 could be obtained.
