Title (EN) LIGHT EMITTING DEVICE
(FR) DISPOSITIF ÉMETTEUR DE LUMIÈRE
Abstract:
(EN) The present invention discloses a semiconductor light emitting device including an active layer for generating light by recombination of electron and hole between a first semiconductor layer having first conductivity and a second semiconductor layer having second conductivity different from the first conductivity, the second semiconductor layer being disposed on the active layer. The semiconductor light emitting device comprises first array including a trench having a first inclination angle, and second array including a trench having a second inclination angle different from the first inclination angle.
(FR) La présente invention concerne un dispositif semi-conducteur émetteur de lumière comprenant une couche active servant à générer la lumière par recombinaison des électrons et des trous entre une première couche semi-conductrice présentant une première conductivité et une seconde couche semi-conductrice présentant une seconde conductivité différente de la première conductivité, la seconde couche semi-conductrice étant disposée sur la couche active. Le dispositif semi-conducteur émetteur de lumière comprend une première matrice comportant une tranchée présentant un premier angle d’inclinaison, et une seconde matrice comportant une tranchée présentant un second angle d’inclinaison différent du premier angle d’inclinaison.
