The article shows that the parameter of the function that approximates the P-I characteristic of an InGaN/GaN LED in the low current range, which determines the degree of nonlinearity of the P-I characteristic, is inversely proportional to the square root of the defects density. This dependence is confirmed by experimentally established strong correlations between this parameter and the level of low-frequency noise of LEDs and the parameters of heterostructure luminescence inhomogeneity in the microplasma breakdown mode. This parameter can be used to assess the defectness of light-emitting heterostructures. Keywords: light-emitting heterostructure, defect density, P-I characteristic, low-frequency noise, microplasma breakdown.
