Illustration, Retrograde Solubility Ammonothermal System (IMAGE)
Caption
An illustrated schematic of a retrograde solubility ammonothermal system designed to grow single crystal nitrides. In new NSF-supported research being conducted by Siddha Pimputkar, an assistant professor of materials science and engineering at Lehigh University, a low temperature, high solubility region contains feedstock and is placed above a hotter zone that contains a suspended single crystal seed. A baffle plate controls the convective fluid motion between the zones, and enables mass transport from the source to the seed -- and ultimately leads to growth and enlargement of the crystal.
