ABSTRACTThe p-n structures was formed by the implantation of Al ions into 6H-SiC n-type films and the thermal annealing. An energy of ions was in the range of 40–90 KeV, an annealing temperature -1700–2100K. We investigated the influence of implantation conditions over the defects electroluminescence of the obtained structures.After fabricating contacts and mesa-structures with areas 500–500μm our devices showed under the current of 20 mW:- integral light power 20μW,- λmax=535 nm, δλmax=80nm.For the first time was fabricated the green electroluminescence source on SiC with the value of efficiency approximated to one of the A3B5 structures, and after encapsulating it will be possible to obtain LEDs with an integral light power up to 80–100μW.

To realize high-efficiency AlGaN-based deep-ultraviolet light-emitting diodes (DUV-LEDs), enhancing their light-extraction efficiency (LEE) is crucial. This paper proposes an aluminum-based sidewall reflector structure that could replace the conventional ceramic-based packaging method. We design optimization simulations and experimental results demonstrated the light power output could be enhanced 18.38% of DUV-LEDs packaged with the aluminum-based sidewall.
