    • openAccess   Dielectric confinement of excitons in type-I and type-II semiconductor nanorods 

      Royo Valls, Miguel; Climente, Juan I.; Movilla, Jose L.; Planelles, Josep Institute of Physics (2011-01-12)
      We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the ...

    • closedAccess   Dopant segregation analysis on Sb:SnO2 nanocrystals 

      Beltran, Armando; Stroppa, Daniel G.; Montoro, Luciano A.; Conti, Tiago G.; Da Silva, Rafael O.; Andres, Juan; Leite, Edson R.; Ramírez, Antonio J. Wiley (2011-08-26)
      The development of reliable nanostructured devices is intrinsically dependent on the description and manipulation of materials properties at the atomic scale. Consequently, several technological advances are dependent on ...

    • closedAccess   Experimental and Theoretical Study on the Structure, Optical Properties, and Growth of Metallic Silver Nanostructures in Ag3PO4 

      Botelho, Gleice; Sczancoski, Júlio César; Andres, Juan; Gracia, Lourdes; Longo, Elson American Chemical Society (2015-02)
      Theoretical and experimental studies were performed on the structure, optical properties, and growth of silver nanostructures in silver phosphate (Ag3PO4). This material was synthesized by the coprecipitation method and ...

    • openAccess   Origin of two-hole triplet splitting in circular quantum dots 

      Climente, Juan I. Elsevier (2012-05)
      Recent photoluminescence spectra of positively charged excitons in InAs/GaAs quantum dots have revealed the existence of large splittings between the View the MathML sourcep-shell triplet sublevels of holes. We provide an ...
