Dimension 100 ± 0.2mm 4 Inch Blue LED GaN Epitaxial Wafer On Sapphire SSP Thickness 5.5 ± 0.5μm
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.
