Descripción del proyecto
THIS PROJECT AIMS AT OBTAINING NEW KNOWLEDGE ON THE PHYSICOCHEMICAL CONTROL MECHANISMS OF MICRO- AND NANOFABRICATION OF DIFFERENT TYPES OF MATERIALS USING PROCESSING TECHNIQUES BASED ON IRRADIATION AND ABLATION WITH PULSED LASERS IN THE NANOSECOND AND FEMTOSECOND DOMAINS, THE PROPOSED ACTIVITY IS FORESEEN TO FIND APPLICATIONS IN TECHNOLOGICAL AREAS OF PHOTONICS, PHOTOVOLTAICS, LIGHT EMITTING DIODES, NONLINEAR OPTICAL SYSTEMS AND BIOMEDICINE, THE PROPOSED OBJECTIVES ARE: THE GENERATION, CHARACTERIZATION AND CONTROL OF NANOSTRUCTURES BY PULSED LASER IRRADIATION AND PULSED LASER DEPOSITION OF METAL AND SEMIMETAL OXIDES AND II-VI SEMICONDUCTORS, STUDIES WILL BE CARRIED OUT TO CONTROL THE SIZE AND STOICHIOMETRY OF CLUSTERS AND NANOAGGREGATES GENERATED IN ABLATION PLUMES AND CHARACTERIZE THEIR REACTIVITY, DYNAMICS AND OPTICAL PROPERTIES, THESE STUDIES WILL AIM AT ESTABLISHING CORRELATIONS WITH THE MORPHOLOGICAL, STRUCTURAL, OPTICAL (LINEAR AND NONLINEAR) AND CHEMICAL PROPERTIES OF DEPOSITED NANOSTRUCTURES, THE DEVELOPMENT OF PROCEDURES FOR LASER CONTROL OF MICRO- AND NANOSTRUCTURES (USING PULSED LASER DEPOSITION AND LASER INDUCED SURFACE STRUCTURING) IN POLYMER AND BIOPOLYMER MATERIALS/SUBSTRATES AND THE INVESTIGATION OF THE EFFECTS OF CONFINEMENT IN TWO DIMENSIONS (NANOLAYERS) AND IN ONE DIMENSION (MICRO- AND NANOCHANNELS) ON THE POLYMER STRUCTURAL AND DYNAMIC PROPERTIES,THE GENERATION, CHARACTERIZATION AND FUNCTIONALIZATION OF CARBON NANOTUBES BASED ON A DUAL INFRARED LASER IRRADIATION APPROACH BY EMPLOYING LASER ABLATION AND LASER-ASSISTED CHEMICAL VAPOUR DEPOSITION, THE DEVELOPMENT OF DIAGNOSTIC PROCEDURES BASED ON THE STUDY OF THE COMPOSITION AND DYNAMICS OF LASER PLASMA AND ABLATION PLUMES IN ORDER TO OBTAIN INSIGHT INTO THE MECHANISMS INVOLVED IN THE GENERATION OF NANOSTRUCTURES, LASER PLASMA PLUMES WILL ALSO BE INVESTIGATED TO CONTROL THE MECHANISMS THAT ALLOW THE SELECTION AND ENHANCEMENT OF SPECIES IN THE PLASMA CONTRIBUTING TO HARMONIC GENERATION,
