Synthesis of single-crystalline one-dimensional LiNbO3 nanowires

Abstract

We report a large-scale synthesis of single-crystalline LiNbO3 nanowires with diameters of 300–400 nm, containing only minor amounts of impurities, using a modified molten salt procedure. The isolated product is composed of rhombohedral-phase LiNbO3 nanowires with the c-axis oriented along its length. Raman investigations further confirm the purity and ferroelectric order of the nanowires and are consistent with electron microscopy data.
