英文摘要
We studied on terahertz quantum cascade lasers(THz-QCLs) using III-Nitride semiconductors, for the realization of the unexplored frequency range 5-12 THz on THz-QCLs. In this study, we fabricated GaN/AlGaN based QCL structures using a droplet elimination by thermal annealing(DETA) technique, and analyzed the structural and electroluminescence properties. We found that DETA is a useful technique which makes it possible not only to increase the number of periods in the QC structure, but also to improve the structural properties of the QC structure. Further, we successfully for the first time observed spontaneous electroluminescence due to intersubband transition with peaks at frequencies from 1.4 to 2.8 THz on the THz-QCL structure fabricated with using the DETA technique.
