Annotation
High power ultraviolet (UV) and violet spectral region light-emitting diodes (LED) with chips based on p–n InGaN/AlGaN/GaN–heterostructures electroluminescence (EL) spectra have been studied [1, 2]. Experimental equipment based on monochromator MDR–12 has been automated; new software providing fast spectral and electrical measurements has been created. Current voltage characteristics and output radiation power dependencies have been analyzed.
