Description
Summary:Metrological possibilities of a specialised measuring complex with which help electroluminescence spectra (EL) light-emitting diodes (LED) are received are studied. The analysis is carried out and forms of spectra of EL LED with a single quantum hole on the basis of model considering penetration into twodimensional active layer InGaN of electric field from barrier layers GaN adjoining to it and AlGaN are investigated. By means of the given model values of effective width of the forbidden zone, Fermi's level, parametre of a exponential tail of density of a condition are received.
