ELASTIC, MAGNETIC AND ELECTROSTATIC PROPERTIES OF HETEROSTRUCTURED COLLOIDAL QUANTIC WELLS

Operation co-funded by EU cohesion policy (European Regional Development Fund (ERDF)) under the programme Multi-regional Spain - ERDF (2014ES16RFOP002), managing authority: Subdirección General de Gestión del FEDER, de la Dirección General de Fondos Europeos del Ministerio de Hacienda.. The source names no beneficiary for this operation. Location: Castellón (NUTS ES522); Spain. Budget: total eligible expenditure EUR 20,570; EU co-financing EUR 10,285 (co-financing rate 50%), as stated by the source. Runs 2018-01-01 to 2020-12-31.

Summary from Kohesio (English machine translation by the source): COLLOIDAL SEMICONDUCTOR NANOPLATELETS ARE THE WET-CHEMISTRY ANALOGOUS OF THE EPITAXIAL QUANTUM WELLS THAT REVOLUTIONISED THE LOW-DIMENSIONAL PHYSICS IN THE 80S AND 90S. SINCE THEIR FIRST SYNTHESIS IN 2008, THERE HAS BEEN INCREASING INTEREST IN THESE NANO-OBJECTS OWING TO THEIR OUTSTANDING OPTICAL PROPERTIES, WHICH OUTPERFORM THOSE OF COLLOIDAL NANOWIRES AND NANOCRYSTALS IN MANY RESPECTS. DESPITE OBVIOUS REMINESCENCES ARISING FROM THE QUASI-2D ELECTRONIC STRUCTURE, NANOPLATELETS PRESENT REMARKABLE DIFFERENCES AS COMPARED TO EPITAXIAL QUANTUM WELLS. THESE INCLUDE CHEAPER FABRICATION COST AND SUPERRADIANCE AT ROOM TEMPERATURE, WHICH MAKE THEM AN APPEALING FOR APPLICATIONS WHERE QUANTUM WELLS HAVE ENTERED THE MARKET -E.G. LASING DEVICES-, BUT ALSO OTHER FUNDAMENTAL ONES, WHICH NEED TO BE PROPERLY UNDERSTOOD IN ORDER TO FULLY EXPLOIT THE PROMISING PROPERTIES OF THESE STRUCTURES. THE LATTER INCLUDE AN INTIMATE INTERACTION WITH ORGANIC LIGANDS PASSIVATING THE SURFACE, THE PRESENCE OF CONTROLLED LATERAL CONFINEMENT AND THE POSSIBILITY TO GROW HETEROSTRUCTURES NOT ONLY PARALLEL TO THE WELL PLANE, BUT ALSO INSIDE THE WELL PLANE ITSELF. THE GOAL OF THE PRESENT PROJECT IS PRECISELY TO INVESTIGATE PROPERTIES AND POSSIBILITIES OF HETEROSTRUCTURED II-VI NANOPLATELETS. CORE/SHELL CDSE/XS (WITH X=CD, ZN) AND CDSE/CDTE NANOPLATELETS HAVE BEEN SYNTHESIZED RECENTLY, AND THEIR STRUCTURAL AND OPTICAL RESPONSE HAVE BEEN CHARACTERIZED EXPERIMENTALLY. THEORETICAL STUDIES HOWEVER LAG BEHIND, LARGELY BECAUSE OF THE DIFFICULTY TO MODEL EXCITONS IN LARGE YET FINITE ANISOTROPIC CRYSTALS, WITH EXTREMELY STRONG ELECTRONIC CORRELATIONS DUE TO THE DIELECTRIC CONTRAST BETWEEN THE INORGANIC OBJECT AND THE ORGANIC ENVIRONMENT. IN THE LAST STAGE OF OUR PREVIOUS PROJECT, WE SUCCEEDED IN DEVELOPING A SEMI-EMPIRICAL (EFFECTIVE MASS) METHOD TO MODEL EXCITONS IN FREE-STANDING NANOPLATELETS ACCOUNTING FOR SUCH EFFECTS. IN THE CURRENT PROJECT WE AIM AT EXTENDING AND APPLYING SUCH A MODEL TO DESCRIBE THE [shortened; the full text is on the Kohesio page]
