    • openAccess   Charge control in laterally coupled double quantum dots 

      Muñoz Matutano, G.; Royo Valls, Miguel; Climente, Juan I.; Canet Ferrer, J.; Fuster, D.; Alonso-Jordá, Pedro; Fernández Martínez, Iván; Martínez-Pastor, Juan P.; González Diez, Yolanda; González Sotos, Luisa; Briones, Fernando; Alen Millán, B. American Physical Society (2011-07-27)
      We investigate the electronic and optical properties of InAs double quantum dots grown on GaAs (001) and laterally aligned along the [110] crystal direction. The emission spectrum has been investigated as a function of a ...

    • openAccess   Dilemmas of dye-sensitized solar cells 

      Bisquert, Juan Wiley-VCH Verlag Berlin (2011)
      Ferrocene to the rescue: The dye-sensitized solar cell allows changes in the energetics of electron transport, molecular absorbers, and hole transport materials to better harvest the energy of solar photons (see picture). ...

    • openAccess   Electrons, holes, and excitons in GaAs polytype quantum dots 

      Climente, Juan I.; Segarra, Carlos; Rajadell Viciano, Fernando; Planelles, Josep American Institute of Physics (2016)
      Single and multi-band k⋅p Hamiltonians for GaAs crystal phase quantum dots are used to assess ongoing experimental activity on the role of such factors as quantum confinement, spontaneous polarization,valence band mixing, ...

    • 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 ...

    • openAccess   Quantum mechanical modeling of excited electronic states and their relationship to cathodoluminescence of BaZrO3 

      Moreira, Mario Lucio; Andres, Juan; Gracia, Lourdes; Beltran, Armando; Montoro, Luciano A.; Varela, José A.; Longo, Elson American Institute of Physics (AIP Publishing LLC) (2013)
      First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** ...

    • openAccess   Two-dimensional Bloch electrons under strong magnetic modulation 

      Movilla, Jose L.; Planelles, Josep American Physical Society (2011-01-13)
      The band structure of a high-mobility two-dimensional electron gas patterned with a square lattice of holes (antidots) is studied theoretically under the influence of a magnetic modulation consisting of perpendicular ...
