• openAccess   Biexcitons in CdSe nanoplatelets: geometry, binding energy and radiative rate 

      Macias-Pinilla, David F.; Planelles, Josep; Climente, Juan I. Royal Society of Chemistry (2022-05-13)
      Biexciton properties in semiconductor nanostructures are highly sensitive to quantum confinement, relative electron–hole masses, dielectric environment and Coulomb correlations. Here we present a variational Quantum Monte ...
    • openAccess   CdSe/CdS/CdTe Core/Barrier/Crown Nanoplatelets: Synthesis, Optoelectronic Properties, and Multiphoton Fluorescence Upconversion 

      Khan, Ali Hossain; Bertrand, Guillaume H. V.; Teitelboim, Ayelet; M, Chandra Sekhar; Polovitsyn, Anatolii; Brescia, Rosaria; Planelles, Josep; Climente, Juan I.; Oron, Dan; Moreels, Iwan American Chemical Society (2020-04-10)
      Colloidal two-dimensional (2D) nanoplatelet heterostructures are particularly interesting as they combine strong confinement of excitons in 2D materials with a wide range of possible semiconductor junctions due to a ...
    • openAccess   Shell filling and paramagnetism in few-electron colloidal nanoplatelets 

      Llusar, Jordi; Climente, Juan I. American Physical Society (2022-08-05)
      Colloidal semiconductor nanoplatelets are excellent optical emitters, which combine a quasi-2D structure with strong in-plane Coulomb interactions. Here, we go beyond the photoexcitation regime and investigate theoretically ...
    • openAccess   Tuning intraband and interband transition rates via excitonic correlation in low-dimensional semiconductors 

      Planelles, Josep; Achtstein, Alexander W.; Scott, Riccardo; Owschimikow, Nina; Woggon, Ulrike; Climente, Juan I. ACS Publications (2018-08)
      We show that electron-hole correlation can be used to tune interband and intra- band optical transition rates in semiconductor nanostructures with at least one weakly confined direction. The valence-to-conduction band ...
    • openAccess   Visible and Infrared Nanocrystal-Based Light Modulator with CMOS Compatible Bias Operation 

      Zhang, Huichen; Guilloux, Victor; Bossavit, Erwan; FU, Ningyuan; Dabard, Corentin; Cavallo, Mariarosa; Dang Huu, Tung; Khalili Lazarjani, Adrien; Abadie, Claire; Alchaar, Rodolphe; Gréboval, Charlie; Xu, Xiang Zhen; Utterback, James; Pierucci, Debora; Ithurria, Sandrine; Climente, Juan I.; Barisien, Thierry; lhuillier, emmanuel American Chemical Society (2023-02-15)
      Nanocrystals are now established light sources, and as synthesis and device integration have gained maturity, new functionalities can now be considered. So far, the emitted light from a nanocrystal population remains mostly ...
