"We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN\r\nlight-emitting diodes (LEDs) may be connected to the current crowding effect. A numerical\r\nmodel of internal quantum efficiency calculation is presented that takes into account\r\nnonuniform lateral carrier injection in the active region. Based on this model, we examine the\r\neffect of current crowding on the efficiency droop using comparison of simulated internal\r\nquantum efficiency of InGaN LEDs with low and high uniformity of current spreading. The\r\nresults of simulations and measurements show that the devices with low uniformity of current\r\nspreading exhibit higher efficiency droop and lower roll-off current value."^^ . "2011" . .
