Abstract

Interfacial phenomena at the liquid/solid interface under high temperatures were observed in real time to understand the growth process of AlN during solid-source solution growth. In this study, we used an AlN/α-Al2O3 template as the substrate; these wide-bandgap materials made the substrate transparent to visible light. Therefore, we observed the morphology of the liquid/solid interface through the template from the bottom. In this investigation, a polycrystal formed because of melt-back etching during the initial stage of growth; nevertheless, we succeeded in obtaining real-time images of interfacial phenomena.
