Abstract

DISPOSITIVO SEMICONDUCTOR PARA GENERAR UN HAZ DE ELECTRONES. EN UNA PALANCA DE SILICIO (1) SE FORMA UNA CAPA DE TIPO <<N>> (3) Y OTRA DE TIPO <> (4), CON UNA ZONA (12) CON MAYOR CONCENTRACION DE IMPUREZA, CON LO QUE SE CONSIGUE UNA TENSION INVERSA MENOR PARA PRODUCIR AVALANCHA DE ELECTRONES. APLICANDO DICHA TENSION LOS ELECTRONES ATRAVIESAN LA CAPA TIPO <<N>> (3), QUE ES MUY DELGADA, PASANDO AL ESPACIO HUECO (8), DONDE ENCUENTRAN UN ELECTRODO ACELERADOR (9), SALIENDO EL HAZ DE ELECTRONES SEGUN LA FLECHA (6).
