    • openAccess   Aharonov-Bohm oscillations and electron gas transitions in hexagonal core-shell nanowires with an axial magnetic field 

      Royo Valls, Miguel; Segarra, Carlos; Bertoni, Andrea; Goldoni, Guido; Planelles, Josep American Physical Society (2015)
      We use spin-density-functional theory within an envelope function approach to calculate electronic states in a GaAs/InAs core-shell nanowire pierced by an axial magnetic field. Our fully three-dimensional quantum modeling ...

    • openAccess   Comparison between Trion and Exciton Electronic Properties in CdSe and PbS Nanoplatelets 

      Macias-Pinilla, David F.; Planelles, Josep; Mora-Sero, Ivan; Climente, Juan I. American Chemical Society (2021-07-07)
      The optoelectronic properties of metal chalcogenide colloidal nanoplatelets are often interpreted in terms of excitonic states. However, recent spectroscopic experiments evidence the presence of trion states, enabled ...

    • openAccess   Lateral Confinement in 2D Nanoplatelets: A Strategy to Expand the Colloidal Quantum Engineering Toolbox 

      Curti, Leonardo; Dabard, Corentin; Makké, Lina; Fu, Ningyuan; Lehouelleur, Henri; Hua, Muchuan; Bossavit, Erwan; Cavallo, Mariarosa; Xu, Xiang Zhen; Pierucci, Debora; Silly, Mathieu G.; Guzelturk, Burak; lhuillier, emmanuel; Climente, Juan I.; Diroll, Benjamin T.; Ithurria, Sandrine Wiley (2024)
      Among colloidal nanocrystals, 2D nanoplatelets offer a unique set of properties with exceptionally narrow luminescence and low lasing thresholds. Furthermore, their anisotropic shape expands the playground for the complex ...

    • openAccess   Morphology and Band Structure of Orthorhombic PbS Nanoplatelets: An Indirect Band Gap Material 

      Macias-Pinilla, David F.; Echeverría-Arrondo, Carlos; Gualdrón Reyes, Andrés Fabián; Agouram, Said; Muñoz-Sanjosé, Vicente; Planelles, Josep; Mora-Sero, Ivan; Climente, Juan I. American Chemical Society (2021-01-12)
      PbS quantum dots and nanoplatelets (NPLs) are of enormous interest in the development of optoelectronic devices. However, some important aspects of their nature remain unclear. Recent studies have revealed that colloidal ...
