Kyma Technologies will develop a cost-effective technique to grow high-quality gallium nitride (GaN) seeds into GaN crystal boules, which are used as the starting material for a number of semiconductor devices. Currently, growing boules from GaN seeds is a slow, expensive, and inconsistent process, so it yields expensive electronic devices of varying quality. Kyma will select the highest quality GaN seeds and use a proprietary hydride vapor phase epitaxy growth process to rapidly grow the seeds into boules while preserving the seed’s structural quality and improving its purity.
If successful, Kyma will produce low-cost, high-performing boules for use in a variety of high-power electronics applications, including power inverters and converters.
Advances in power electronics could facilitate greater adoption of electric vehicles, which in turn could help reduce U.S. oil imports.
More efficient power electronics systems promise reduced electricity consumption, resulting in fewer harmful energy-related emissions.
More efficient power electronics would use less energy, saving American families and business owners money on their power bills.
