Abstract

L'invention concerne les dispositifs photoémissifs à semi-conducteur. Elle se rapporte à un dispositif photoémissif dans lequel un trou débouchant 4 est formé dans un substrat semi-conducteur 2. Une jonction pn est formée par diffusion d'impureté qui forme une région active 31. Une électrode 1 est disposée sur la région active et éventuellement sur une face du substrat 2, et une autre électrode est formée sur l'autre face. La lumière créée par la région active 31 est dirigée préférentiellement en direction perpendiculaire à la grande face du substrat 2. Application aux dispositifs d'affichage. (CF DESSIN DANS BOPI)
