Abstract

Single-crystalline KNbO₃ nanocubes with orthorhombic phase were prepared in a large scale by a simple one-step molten salt route without using any surfactant as template; the nanostructures exhibited high piezoelectric properties such as d₃₃ = 105 pC/N and k_p = 0.34 as piezoelectric materials.
