Abstract
SE PRESENTAN UN CATODO DE EMISION DE CAMPO MEJORADO Y METODOS PARA FABRICAR EL CATODO. EN LOS METODOS DE LA INVENCION, EL CATODO DE EMISION DE CAMPO SE FABRICA A PARTIR DE AL MENOS UN CUERPO QUE CONTIENE UNA PRIMERA SUSTANCIA. EL METODO INCLUYE: PREPARAR LAS IRREGULARIDADES EN LA SUPERFICIE EMISORA DEL CUERPO, AÑADIR A LA SUPERFICIE EMISORA DEL CUERPO IONES DE UNA SEGUNDA SUSTANCIA CON UNA BAJA FUNCION DE TRABAJO, Y MODIFICAR LA SUPERFICIE EMISORA INDUCIENDO LA EMISION DE CAMPO AL APLICAR AL CUERPO UN CAMPO ELECTRICO VARIABLE Y AUMENTAR LA FUERZA DEL CAMPO.
