Power light emitting diode and method with current density operation |
| 摘要 |
A light emitting diode device emitting at a wavelength of 390-415 nm has a bulk gallium and nitrogen containing substrate with an active region. The device has a current density of greater than about 175 Amps/cm2 and an external quantum efficiency with a roll off of less than about 5% absolute efficiency. |
