MUCHOS DE LOS ESPECTACULARES AVANCES TECNOLOGICOS QUE HEMOS VISTO EN LAS ULTIMAS DECADAS ESTAN BASADOS EN NUESTRA CAPACIDAD DE CONTROLAR Y MANIPULAR ELECTRONES A LO LARGO DE UN CIRCUITO, MEDIANTE LA UTILIZACION DE DISPOSITIVOS DE ESTADO SOLIDO COMO LOS DIODOS Y LOS TRANSISTORES. LA DISIPACION DE CALOR ES UN EFECTO SECUNDARIO NO DESEADO DEL FUNCIONAMIENTO DE ESTOS COMPONENTES Y UN MANEJO ADECUADO DE ESA ENERGIA TERMICA ES UNA TAREA IMPRESCINDIBLE PARA MANTENER LAS CONDICIONES OPTIMAS DE FUNCIONAMIENTO DE LOS DISPOSITIVOS. LOS FONONES, LAS CUASI-PARTICULAS QUE REPRESENTAN MODOS DE VIBRACION ELEMENTALES DE UNA RED CRISTALINA, SON LOS PRINCIPALES RESPONSABLES DEL TRANSPORTE DE CALOR EN SOLIDOS CRISTALINOS AISLANTES. ALCANZAR UN CONTROL SOBRE LA PROPAGACION DE FONONES SIMILAR AL CONSEGUIDO SOBRE LOS ELECTRONES CREARIA UNA TECNOLOGIA COMPLETAMENTE NUEVA CON APLICACIONES EN EL ALMACENAMIENTO DE DATOS Y DE COMPUTACION, BASADA ENTERAMENTE EN EL CONTROL SOBRE LA TRANSMISION DE CALOR: LA LLAMADA "FONONICA". SIN EMBARGO, CON EL FIN DE PROCESAR LAS CORRIENTES DE FONONES CON EFICACIA Y HACER DE ESTA POTENCIAL TECNOLOGIA UNA REALIDAD, ES IMPRESCINDIBLE EL DISEÑO Y LA REALIZACION EXPERIMENTAL DE DISPOSITIVOS TERMICOS NO LINEALES, CUYA OPERATIVIDAD PUEDA SER MODIFICADA A VOLUNTAD POR UN ESTIMULO EXTERNO. DE HECHO, EL DISEÑO DE RECTIFICADORES Y TRANSISTORES TERMICOS ES UN CAMPO EMERGENTE MUY ACTIVO, CON UN ENORME POTENCIAL DE DESARROLLO EN UN FUTURO PROXIMO. _x000D_ EN ESTE PROYECTO PROPONEMOS EL DISEÑO DE UN NUEVO TIPO DE DISPOSITIVO TERMICO ACTIVO: UNA VALVULA DE FONONES. EN PARTICULAR, SE PROPONE LA UTILIZACION DE MATERIALES FERROELECTRICOS-FERROELASTICOS Y MULTIFERROICOS PARA CREAR BARRERAS ARTIFICIALES PARA LA PROPAGACION DE FONONES QUE PUEDEN MODIFICARSE A VOLUNTAD POR UN CAMPO EXTERNO. LAS PAREDES DE DOMINIO (DWS) FERROICAS HAN DEMOSTRADO COMPORTARSE COMO CENTROS DE DISPERSION EFICACES PARA FONONES. EN ESTE PROYECTO PROPONEMOS EL USO DE ESTA PROPIEDAD, JUNTO CON LA POSIBILIDAD DE MODIFICAR LA DENSIDAD Y DISTRIBUCION DE LOS DOMINIOS FERROICOS EN ALGUNOS MATERIALES POR LA APLICACION DE UN CAMPO ELECTRICO/MAGNETICO, PARA CONTROLAR LA PROPAGACION DE FONONES A TRAVES DEL MATERIAL. ESTE AMBICIOSO OBJETIVO SE ABORDARA MEDIANTE DOS ESTRATEGIAS DIFERENTES:_x000D_ I) MEDIANTE EL USO DE DWS FERROICAS DISTRIBUIDAS AL AZAR EN SISTEMAS FERROELECTRICOS Y MULTIFERROICOS PARA ACTUAR COMO CENTROS DE DISPERSION DE FONONES QUE SE PROPAGAN DE FORMA INCOHERENTE._x000D_ II) POR ARREGLOS PERIODICOS DE LAS DWS EN SUPERESTRUCTURAS CON UN TRANSPORTE COHERENTE DE FONONES, CREANDO CRISTALES FONONICOS ARTIFICIALES._x000D_ DADA LA NATURALEZA NO VOLATIL DE LAS PAREDES DE DOMINIO (LA CONFIGURACION DE LAS PAREDES DE DOMINIO ES ESTABLE UNA VEZ QUE SE ELIMINA EL CAMPO EXTERNO) EL SISTEMA PERMANECERA EN UN ESTADO DE CONDUCTIVIDAD TERMICA ALTA/BAJA HASTA QUE ESTA CONFIGURACION SE MODIFIQUE NUEVAMENTE. POR LO TANTO, LA VALVULA DE FONONES FUNCIONARA COMO UN NUEVO TIPO DE MEMORIA TERMICA DE ESTADO SOLIDO. ADEMAS, LA OPERACION DE LA VALVULA DE FONONES NO SE LIMITA A UN INTERVALO DE TEMPERATURA LIMITADO ALREDEDOR DE UNA TRANSICION DE FASE DADO. EN PRINCIPIO, UN DISPOSITIVO DE ESTE TIPO DEBERIA FUNCIONAR EN UN AMPLIO INTERVALO DE TEMPERATURAS POR DEBAJO DE LA TRANSICION FERROELECTRICO-FERROELASTICA EN EL QUE LOS DOMINIOS FERROICOS SON ESTABLES._x000D_ ESTAS ESTRATEGIAS SON INNOVADORAS Y TENDRAN SIN DUDA UN IMPACTO SIGNIFICATIVO, CONSTITUYENDO UNA VALIOSA CONTRIBUCION AL CAMPO Y AL DESARROLLO DE UNA NUEVA TECNOLOGIA.

MANY OF THE SPECTACULAR TECHNOLOGICAL ADVANCES WE HAVE SEEN IN THE LAST DECADES ARE BASED ON OUR ABILITY TO CONTROL AND MANIPULATE ELECTRONS ALONG A CIRCUIT, USING SOLID STATE DEVICES SUCH AS DIODES AND TRANSISTORS. HEAT DISSIPATION IS AN UNWANTED SIDE EFFECT OF THE OPERATION OF THESE COMPONENTS AND PROPER HANDLING OF THIS THERMAL ENERGY IS AN ESSENTIAL TASK TO MAINTAIN THE OPTIMAL OPERATING CONDITIONS OF THE DEVICES. THE PHONONS, THE QUASI-PARTICULAE REPRESENTING ELEMENTARY VIBRATION MODES OF A CRYSTALLINE NETWORK, ARE PRIMARILY RESPONSIBLE FOR THE TRANSPORT OF HEAT IN INSULATING CRYSTALLINE SOLIDS. ACHIEVING A CONTROL OVER THE PROPAGATION OF PHONONS SIMILAR TO THAT ACHIEVED OVER ELECTRONS WOULD CREATE A COMPLETELY NEW TECHNOLOGY WITH APPLICATIONS IN DATA STORAGE AND COMPUTATION, BASED ENTIRELY ON THE CONTROL OVER HEAT TRANSMISSION: THE SO-CALLED “FONONICAL”. HOWEVER, IN ORDER TO PROCESS PHONON CURRENTS EFFECTIVELY AND MAKE THIS TECHNOLOGICAL POTENTIAL A REALITY, IT IS ESSENTIAL TO DESIGN AND EXPERIMENTALLY PERFORM NONLINEAR THERMAL DEVICES, WHOSE OPERATIVITY CAN BE MODIFIED AT WILL BY AN EXTERNAL STIMULUS. IN FACT, THE DESIGN OF THERMAL RECTIFIERS AND TRANSISTORS IS A VERY ACTIVE EMERGING FIELD, WITH ENORMOUS POTENTIAL FOR DEVELOPMENT IN THE NEAR FUTURE. _x000D_ in this project we PROPONE THE DESIGN OF A NEW ACTIVE TERMIK DISPOSITION TYPE: A VALVE OF PHONONS. IN PARTICULAR, IT IS PROPOSED THE USE OF FERROELECTRIC-FERROELASTIC AND MULTIFERROIC MATERIALS TO CREATE ARTIFICIAL BARRIERS FOR THE PROPAGATION OF PHONONS THAT CAN BE MODIFIED AT WILL BY AN EXTERNAL FIELD. FERROICAS DOMAIN WALLS (DWS) HAVE BEEN SHOWN TO BEHAVE AS EFFECTIVE DISPERSION CENTERS FOR PHONONS. IN THIS PROJECT WE PROPOSE THE USE OF THIS PROPERTY, ALONG WITH THE POSSIBILITY OF MODIFYING THE DENSITY AND DISTRIBUTION OF THE FERROIC DOMAINS IN SOME MATERIALS BY THE APPLICATION OF AN ELECTRIC/MAGNETIC FIELD, TO CONTROL THE PROPAGATION OF PHONONS THROUGH THE MATERIAL. This OBJECTIVE AMBICIOUS will be addressed by two DIFFERENT STRATEGYS:_x000D_I) MEDIANT THE USE OF FERROICE DWS DISTRIBUTED TO LARAR IN FERROELECTERIC AND Multiferroic SYSTEMS TO ACT AS FOON DISPERSION CENTRES that propagate from INCOHERENT FORMMA._x000D_ II) BY DWS PERIODICAL ARREGES IN Superstructures WITH A COHERENT TRANSPORT OF FOONONS, CREANING ARTIFICIAL FONONICAL CRISTALS._x000D_ GIVE THE NON-VOLATIL NATURALITY OF DOMINY WORKS (THE CONFIGURATION OF DOMAIN WORKS IS STABLE ON THE EXTERNAL CHANGE) SYSTEM will remain in a state of high/lower therapeutic condition that this trust is changed again. THEREFORE, THE PHONON VALVE WILL FUNCTION AS A NEW TYPE OF SOLID STATE THERMAL MEMORY. MOREOVER, THE OPERATION OF THE PHONON VALVE IS NOT LIMITED TO A LIMITED TEMPERATURE RANGE AROUND A GIVEN PHASE TRANSITION. In the first place, a dispossession of this type should operate in an international expansion of weather conditions for the reduction of the FERROELECTRICO-FERROELASTICAL TRANSCISION in which the ferroic dominoes ARE STABLE._x000D_ these strategies are innovators and remain free of a SIGNIFICAT IMPACT, constituting a VALIOUS CONTRIBUTION TO THE CAMP AND DEVELOPMENT OF A NEW TECHNOLOGY.
