Decoupling contact and mirror: an effective way to improve the reflector for flip-chip InGaN/GaN-based light-emitting diodes

Zhu B.; Liu W.; Lu S.; Zhang, Y.; Hasanov N.; Zhang X.; Ji Y.; Zhang Z.-H.; Tan S.T.; Liu, H.; Demir, Hilmi Volkan (Institute of Physics Publishing, 2016)

In the conventional fabrication process of the widely-adopted Ni/Ag/Ti/Au reflector for InGaN/GaN-based flip-chip light-emitting diodes (LEDs), the contact and the mirror are entangled together with contrary processing ...
Modulating ohmic contact through InGaxNyOz interfacial layer for high-performance InGaN/GaN-based light-emitting diodes

Zhu B.; Tan S.T.; Liu W.; Lu S.; Zhang, Y.; Chen, S.; Hasanov N.; Kang, X.; Demir, Hilmi Volkan (Institute of Electrical and Electronics Engineers Inc., 2016)

We report the improved performance of InGaN/GaN-based light-emitting diodes (LEDs) through the design and the formation of the InGaxNyOz interfacial layer, which maintains high reflectivity of silver and forms good ohmic ...
