Droop improvement in high current range on PSS-LEDs

The droop property of blue GaN light emitting diodes (LEDs) has been improved by creating a 9 quantum well (QW) LED on a patterned sapphire substrate (PSS). The droop ratio was improved from 45.9% to 7.6%. At a wavelength of 447 nm, and with standard on-header packaging, the 9QW PSS-LED had an outpu...
