    • 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   Dominant channels of exciton spin relaxation in photoexcited self-assembled (In,Ga)As quantum dots 

      Liao, Yu-Huai; Climente, Juan I.; Cheng, Shun-Jen American Physical Society (2011-04-22)
      We present a comprehensive theoretical investigation of spin relaxation processes of excitons in photoexcited self-assembled quantum dots. The exciton spin relaxations are considered between dark- and bright-exciton states ...

    • openAccess   Emission spectrum of quasiresonant laterally coupled quantum dots 

      Royo Valls, Miguel; Climente, Juan I.; Planelles, Josep American Physical Society (2011-12-21)
      We calculate the emission spectrum of neutral and charged excitons in a pair of laterally coupled InGaAs quantum dots with nearly degenerate energy levels. As the interdot distance decreases, a number of changes take place ...
