Abstract
L'INVENTION CONCERNE UNE STRUCTURE DESTINEE A OSCILLER EN MODE DIT A "TEMPS DE TRANSIT" (MODE IMPATT DE LA TERMINOLOGIE ANGLO-SAXONNE). POUR AMELIORER LE RENDEMENT, ON CHERCHE A AVOIR UNE ZONE D'AVALANCHE LIMITEE A L'EPAISSEUR D'UNE COUCHE MINCE D'UN MATERIAU SEMICONDUCTEUR DIFFERENT DE CELUI QUI CONSTITUE LA ZONE DE TRANSIT. LA STRUCTURE SELON L'INVENTION COMPORTE UNE COUCHE METALLIQUE 1, UNE COUCHE DE GERMANIUM 2 A FORTE RESISTIVITE A FAIBLE TENSION DE CLAQUAGE, EPITAXIEE SUR UN SUBSTRAT 3 EN ARSENIURE DE GALLIUM MONOCRISTALLIN. LE DOPAGE DU GERMANIUM EST A FAIBLE TAUX, CELUI DE L'ARSENIURE DE GALLIUM EST PLUS ELEVE (ET DE TYPE N), DE MANIERE A AVOIR UN CHAMP CRITIQUE PLUS ELEVE QUE CELUI DU GERMANIUM. APPLICATION A LA GENERATION D'HYPERFREQUENCES.
