“…To quantify IQE, very often the so-called ABC model is employed: 6,7
Here, N denotes the carrier density, while A , B , and C are recombination coefficients ascribed to Shockley–Read–Hall (SRH), band-to-band, and intrinsic Auger recombination, respectively. Eqn (1) is attractive due to its simplicity, but its applicability to electrically driven LEDs is questionable as it cannot account for the complexity of carrier cross-well transport in disordered InGaN, 8,9 which makes the N distribution within an LED unclear. On the other hand, the standard ABC model with only slight modifications ( e.g.…”
