“…However, flux growth is not conducive to the growth of large, oriented crystals which are required for commercial devices. Several researchers have grown PMNT single crystals using the Bridgman method which does allow for the growth of large, oriented crystals [12][13][14][15][16][17][18][19][20][21]. Compositional variations along the growth direction were found to be a major problem in using this method [14,15,[17][18][19], resulting in large portions of the grown boules with non-optimal piezoelectric properties.…”
