Abstract

Investigations were conducted to explore the effect of Al_0.3Ga_0.7N/GaN short-period superlattice (SPSL)-inserted structures in the GaN under layer on the performance of In_0.2Ga_0.8N/GaN multiple quantum well (MQW) light emitting diodes (LEDs). The Al_0.3Ga_0.7N/GaN SPSL-inserted LEDs were found to exhibit improved materials and device characteristics including decrements in ideality factor and reverse leakage current. The results of etch pit counts reveal that SPSL-induced threading dislocation density reduction in the SPSL-inserted In_0.2Ga_0.8N/GaN MQW LED structures enables the improved LED performance.
