"size effect of aluminum gallium indium phosphide (AlGaInP) red Micro-LEDs on silicon substrate. The researchers adopted a low-damage etching formula and silicon substrates with better heat dissipation to avoid the light absorption properties of GaAs substrates. Experimental results show that smaller micro-LEDs have smaller leakage current and larger series resistance and can withstand higher current density without the current crowding effect"
