It is found that, when T is decreased slightly to 140 K, the EL intensity efficiently increasesdue to reduced non-raiative recombination processes. However, further decrease of T below 100 K, itdrastically decreases due to the reduced carrier capturing by the localized recombination centers andshows a clear trend of saturation, accompanying decreases of the EL differential efficiency. Theseresults are analyzed within a context of rate equation model assuming a finite number of radiativerecombination centers.}, pages = {44--48}, title = {Temperature and current dependent capture of injected carriers in InGaN single-quantum-well light-emitting diodes}, volume = {192}, year = {2002}, yomi = {サタケ, アキヒロ and フジワラ, ケンゾウ} }
