摘要: Excessive depth of optically active quantum wells (QWs) and related increase in QW population capacity is one the main causes inhomogeneous carrier injection unequal populations multiple-quantum-well III-nitride light emitters operating visible range. In turn, uneven distribution injected carriers across device's region creates imbalance between confined electron hole supports large residual charges, especially marginally located n-side p-side QWs. charges are strongly non-equilibrium as determined by dynamic balance capture recombination rates, with later being progressively faster excessively deep
