【 摘 要 】

The blue light-emitting structures based on solid solutions of the system AlGaInN that contained superlattices In0.9Ga0.1N/In0.99Ga0.01N and Al0.15Ga0.85N/GaN were investigated, and its basic parameters and characteristics were defined. The main difference between the samples was an "upper blocking layer" that formed by AlGaN solid solutions with a different stoichiometric composition or as a superlattice. Spectral and thermal investigations of samples were conducted, and the temperatures of the active region were calculated. The optimal types of structures for different operation modes were offered.
