Recently proposed double-scaled potential profile model is used to reveal the scale of potential fluctuations in the individual In-rich regions as well as the dispersion of the average exciton localization energy in these regions. The influence of the different potential fluctuation scales on the stimulated emission threshold and luminescence decay time of highly excited InGaN active layers is studied.}, title={Photoluminescence spectroscopy for the evaluation of band potential roughness of InGaN active layers}, type={artykuł}, keywords={optyka, photoluminescence, InGaN quantum wells, Monte Carlo simulation, exciton hopping}, }
