Toshiba Breaks the Green Gap in LEDs

Toshiba's Tamonari Shioda has presented the company’s new discovery about the green gap in LEDs at the ninth International Conference on Nitride Semiconductors (ICNS).

Currently, the green gap in LEDs is that the rapidly declining efficiency of green light emitters at longer and longer wavelengths.

According to Toshiba's Tamonari Shioda, by inserting thin AlGaN layers in the active region of a conventional device, this approach could increase the output power of green LEDs by a factor of almost ten.
