Descripción del proyecto
THE PRESENT PROPOSAL IS FOCUSED ON THE DEVELOPMENT OF THIN-FILM THERMOELECTRIC GENERATORS BASED ON RIGID AND FLEXIBLE SUBSTRATES FOR THE NEXT GENERATION OF HEAT HARVESTING DEVICES WITH SEAMLESS INTEGRATION CAPABILITIES. THE FILMS WILL CONSIST OF METAL CHALCOGENIDES (MC), WITH RECORD VALUES OF THERMOELECTRIC EFFICIENCY WHEN USED AS MONOCRYSTALLINE MATERIALS. WE WILL FILL OUT THE SCARCE INFORMATION ON THIN FILM GROWTH OF MC BY ANALYZING ALL THE PARAMETERS INVOLVED IN THE PROCESS AND OPTIMIZE THEM. RADIO-FREQUENCY MAGNETRON SPUTTERING WILL BE THE FABRICATION METHOD OF CHOICE AS THE OPTIMAL GROWTH TECHNIQUE GIVEN THE STRAIGHTFORWARD TRANSFERABILITY TO THE INDUSTRY. A GLOBAL ANALYSIS OF THE MATERIALS, THIN FILMS, AND DEVICES WILL BE PERFORMED USING PHYSICAL CHARACTERIZATION TECHNIQUES, DENSITY FUNCTIONAL THEORY AND SIMULATIONS BASED ON FINITE ELEMENTS. ADDITIONALLY, THE INCORPORATION OF A MAGNETIC METAL WILL ALLOW THE IMPLEMENTATION OF NEW FUNCTIONALITIES IN OUR THERMOELECTRIC DEVICES. THE DESIGN, LOOKING FOR THE MAXIMUM RECYCLABILITY, WILL BE DISCUSSED AND EVALUATED. THE INTEGRATION OF HIGH QUALITY ULTRATHIN THERMOELECTRIC MATERIALS AND HETEROSTRUCTURES WILL HAVE A DECISIVE IMPACT IN THE DEVELOPMENT OF THERMOELECTRIC GENERATORS WITH HIGH POWER AND NOVEL FUNCTIONALITIES.
