Abstract:We investigated 590 nm light-emitting diodes appropriate for full-color display applications in terms of their electrical and optical behaviors during operation according to their Mg doping profile in the p-cladding layer. As the hole concentration in the "b" zone of the p-cladding layer is increased from 3.4 x 10(17) to 6.7 x 10(17), the light output power increases by 41% due to the enhancement of the hole injection into the active region and also due to the minimization of the carrier overflow problem.
