fact sheet

Livermore Lab is working with light-emitting-diode (LED) manufacturer SORAA to create a new computer model of the company’s research-scale process for growing gallium nitride (GaN) crystals.

Impact

iconWorking to reduce costs and manufacturing time for next-generation LEDs.
iconUsing Livermore supercomputers, the Lab worked with SORAA to create a new computer model of the company’s research-scale process for growing GaN crystals.
iconSORAA simulations took a week to complete, reducing processing time by 10x.
iconSimulation results revealed a more complicated flow structure than anticipated and provided improved predictions of local temperatures and flow velocities.
iconSORAA is in a better position to grow GaN crystals by using the best performing designs which will then be tested to produce large, production-scale reactors.
