Improved Silicon-Substrate LEDs Address High Solid-State Lighting Costs
The dominant technology for today’s high-brightness LEDs is gallium nitride (GaN) on sapphire, silicon carbide (SiC), or silicon-substrate LEDs. These materials are popular because the resultant LEDs are bright, efficient, and last a long time. However, the chips are tough to manufacture and package into useable devices, multiplying the cost of end products that use […]
