4 inch Blue LED GaN epitaxial wafer on sapphire SSP
Researchers from North Carolina State University and Purdue University have shown that the semiconductor material gallium nitride (GaN) is non-toxic and is compatible with human cells – opening the door to the material's use in a variety of biomedical implant technologies.
LEDs, light emitting diodes, are light sources that are energy efficient and can be made in a variety of colors. Gallium is a main component in many LED lights, with different gallium compounds producing different colored light when exposed to an electric current.
