Σύνθεση και χαρακτηρισμός χαμηλοδιάστατων ημιαγωγών αλογονιδίων του μολύβδου και χαλκογενιδίωνΜαράτου, Ευαγγελία 08 July 2011 (has links)
Στην μεταπτυχιακή εργασία ειδίκευσης περιγράφεται η σύνθεση και ο χαρακτηρισμός νέων υβριδικών ανόργανων-οργανικών χαμηλοδιάστατων ημιαγωγών βασισμένων σε αλογονίδια του μολύβδου και διαφόρων χαλκογενιδίων μετάλλων για οπτικές και οπτικοηλεκτρονικές εφαρμογές. Για να γίνουν κατανοητές οι σχετικές έννοιες των χαμηλοδιάστατων ημιαγωγών αρχικά αναφερόμαστε στην κρυσταλλική δομή των στερεών, τη σχετική θεωρία των ενεργειακών ζωνών και ειδικότερα στους ημιαγωγούς. Με βάση αυτά αναπτύσσεται η θεωρία για τα χαμηλοδιάστατα ημιαγώγιμα συστήματα και ερμηνεύονται τα σχετικά κβαντικά φαινόμενα. Ειδικότερα, εξηγείται πως οι ιδιότητες που υπάρχουν στους τρισδιάστατους ημιαγωγούς αλλάζουν όταν το μέγεθος αυτών τροποποιηθεί και αποκτήσουν κάποια από τις τρεις διαστάσεις στην κλίμακα του νανομέτρου. Γίνεται αναφορά στους διάφορους τρόπους σύνθεσης νέων χαμηλοδιάστατων συστημάτων, στη μορφολογία τους καθώς και στις ιδιότητες και μεθόδους χαρακτηρισμού με έμφαση στις οπτικές και ηλεκτρονικές ιδιότητές τους. Τέλος, δίνονται πρώτα αποτελέσματα διαφόρων χαμηλοδιάστατων ημιαγώγιμων συστημάτων μαζί με τη φασματοσκοπική και ηλεκτρική ανάλυση τους. Επίσης, αναλύονται οι ιδιότητες τους σε σχέση με απλά μοντέλα και συζητείται η εφαρμογή των συγκεκριμένων σε πιθανές εφαρμογές με βάση τις οπτικές ιδιότητες τους. / In this master thesis it is described the synthesis and the characterization of hybrid inorganic - organic low dimensional semiconductors based on lead halides and various metal chalcogenides for optical and optoelectronics applications. In order to become more comprehensive, the relative notions of low dimensional semiconductors, we initially report on the theory of energy bands for crystalline solids and more specifically for semiconductors. In such a context, the theory for the low dimensional semiconductor systems is presented and is interpreted in terms of the quantum theory. More specifically, we explain that properties that exist in the three-dimensional semiconductors change when these formed in such a way that one of their dimensions are in the nanometric scale. Also, report is being given in the various methods of synthesis of new low dimensional systems, in their morphology as well as in the attributes and methods of characterization with emphasis in the optical and electronic attributes. Finally, first results of new low dimensional semiconductors systems are presented along with their optical and electric characterization. Also, their attributes are analyzed concerning simple models as well as their application is discussed in possible applications with basis their optical attributes.

Quantum dots and their interaction with biomoleculesStanisavljević, Maja January 2015 (has links)
In this study CdTe QDs were synthetized via microwave irradiation method. Further they have been modified for purposes of their interaction with biomolecules using different conjugation approaches. Applied conjugation chemistries were non-specific interaction, streptavidin-biotin affinity. Glutathione modified CdTe QDs of 2 nm size were capable of non-specific interaction with major groove of DNA, while streptavidin modified CdTe QDs served as specific linker for biotinylated oligonucleotides. Further, streptavidin-biotin interaction was used for coupling of apoferritin and magnetic nanoparticles.
