| Research Abstract |
In this paper, we have investigated the growth of KN plate crystals with rectangular shape, similar to the device dimensions, from the melt with a stoichiometric composition, by means of the μ-PD method. The cylindrical platinum crucible with rectangular nozzle (5mm×1mm, height 2mm and 0.4 mm hole at a center) has been used, stabilizing the solid-liquid interface during the growth in order to keep the crystal shape uniformly. As a result, plate KN crystal with 35mm long, 4mm width and 1.5 mm thickness has been successfully grown.
