Developing machining technologies for single crystal gallium oxide (2018–2020)
Gallium oxide is a new semiconductor material that can be used to make diodes and transistors with lower loss than Si, and power electronic devices with lower cost and better performance than SiC and GaN. The use of such a material can thus ease the global energy crisis. To further progress gallium oxide semiconductor based technologies, cost-effective machining processes must be developed. The proposed research aims to understand the nature of deformation and removal of this unique class of materials during machining. A successful outcome will not only develop an enabling machining technology for this next generation power semiconductor, but new understanding of machining and materials science will be generated.
