Abstract

UN DISPOSITIVO FERROELECTRICO DE CRISTAL LIQUIDO ESTA COMPUESTO DE UNA CAPA DE MATERIAL FERROELECTRICO DE CRISTAL LIQUIDO ENTRE DOS PAREDES CELULARES CON ESTRUCTURAS DE ELECTRODOS Y UN TRATAMIENTO DE ALINEACION DE LA SUPERFICIE. LA ALINEACION DE LA SUPERFICIE SE DEBE A UNA SUPERFICIE PERFILADA, I.E. UNA RETICULA EN AL MENOS UNA DE LAS PAREDES CELULARES. LA RETICULA PUEDE SER MONORRETICULAR O BIRRETICULAR, CON UN PERFIL SIMETRICO O ASIMETRICO. UN TAL PERFIL PERMITE UNA INCLINACION Y ALINEACION DE LA SUPERFICIE QUE ANCLA LA ENERGIA PARA DISPONERLA DE FORMA INDEPENDIENTE DE MODO QUE SE AJUSTE AL MATERIAL DE CRISTAL LIQUIDO Y AL TIPO DE DISPOSITIVO PARA PROPORCIONAR LA DISPOSICION MOLECULAR REQUERIDA Y UN BAJO NIVEL DE DEFECTO DEL DISPOSITIVO. LA RETICULA PUEDE OBTENERSE POR INTERFEROGRAFIA, FOTOLITOGRAFIA, GRABADO EN RELIEVE, RAYADO O TRANSFERENCIA DE LA CAPA PORTADORA. LAS DIRECCIONES DE LA ALINEACION EN LAS PAREDES CELULARES PUEDEN SER PARALELAS O NO PARALELAS. LA INCLINACION DE LA SUPERFICIE EN AMBAS PAREDES CELULARES PUEDE TENER EL MISMO O DIFERENTES VALORES. LAS PAREDES CELULARES PUEDEN SER RELATIVAMENTE RIGIDAS, P.EJ. PLACA DE VIDRIO O FLEXIBLES, I.E. PLASTICO FINO QUE PUEDE TENER SU CARA INTERNA GRABADA EN RELIEVE PARA DAR UNA O AMBAS, UNA RETICULA Y UN PAR DE PILAR ESPACIADORES.
