Project Abstract:

GaN-based materials and devices are widely applied in blue/green, UV optical and electronic devices. The GaN group, headed by Prof Chua Soo Jin has fabricated the UV/ visible LEDs and is equipped with facilities for the III-nitride materials growth, characterization and device processing. This piece of work is done in collaboration with IMRE and chemistry department. Assoc Prof Loh Kian Ping’s group in the chemistry department has fabricated ZnO and BN nanostructure on different substrates with various growth methods. This project will combine the strength of both groups to grow AlGaInN / ZnO and AlInGaN / BN hetero-nano structures with the aim of achieving highly efficient visible LEDs. AlGaInN/ZnO and AlGaInN/BN structures can be used to fabricate novel high efficiency light emitting devices because of the much larger active area which can be obtained when using nano-hetero-structure as active layer compared with the ordinary planar devices. Furthermore, The AlInGaN/BN and AlInGaN/ZnO will have many novel properties due to the low dimensional structures. These properties will be investigated in this project.
