a Size-dependent EQE of AlGaInP/GaInP micro-LED. b Peak current density of LED devices (symbol) and the current density range 1% apart from peak current density (line) with (left) and without passivation (right). c The EQE plot fitting based on the ABC model. d Size-dependent SRH parameters were used in fitting the EQE curves with and without passivation. The surface recombination velocity is extracted from the slope
