Abstract (en)
[origin: WO2020240140A1] The invention relates to an optoelectronic device (10) comprising first and second light-emitting diodes (11), each LED (11) comprising: a first semiconductor portion (112), with a first type of doping, having a wire-like shape along an axis (11b) and having side surfaces (112b) parallel to this axis; an active portion (111) arranged at least partially on a top end (11a) of the first portion (112); a second semiconductor portion (113), with a second type of doping, arranged at least partially on all or part of the active portion (111); an electrically resistive layer (114) having an electrical resistance that is higher than that of the active portion (111), covering at least all or part of the side surfaces (112b) of the first portion (112) and all or part of the surface of the top end (11a) of the first portion (112) not covered by the active portion (111). The resistive layers (114) of the first and second LEDs are separated from one another.
