electrical engineering energy LED OLEDs MOCVD

In this seminar, the science of MOCVD, the material science of InGaN, and the new-born InGaN-based red LED performance will be discussed. The three primary colors in light are RGB. Green and blue LEDs have been realized by using InGaN active region. The current red LEDs are based on AlGaAs or InGaP as the active region. If we can realize red LEDs by InGaN, it is possible to integrate RGB LEDs in a wafer. Such RGB integration is a breakthrough to develop the next displays, so-called, micro-LED displays that are the next after the OLED displays, and functional LED lightings.

Anwar Gasim obtained a Master's degree in Electrical Engineering under the supervision of Professor Boon Ooi at Photonics Laboratory at King Abdullah University Of Science and Technology (KAUST). He completed his courses and worked on his thesis which was on the topic of solid-state lighting. With 20% of the energy produced worldwide being spent on lighting, it is not surprising that the conventional light sources that we use are inefficient. Switching to solid-state lighting, which is based on LEDs, could cut this figure by half. The most promising material for the development of inherent
