The variation in substrate thickness will be included in the calculation and the results can provide detailed insight for the optimization of the micro/mini LED structures. ? 2020 SPIE.Gallium nitride; III-V semiconductors; Nitrides; Color shifts; Color variations; microLED; miniLED; Substrate thickness; Light emitting diodesconference paper10.1117/12.25505062-s2.0-85082674924
