    • openAccess   Coulomb interaction signatures in self-assembled lateral quantum dot molecules 

      Zhou, Xinran R.; Lee, Jihoon H.; Salamo, Gregory J.; Royo, Miquel; Climente, Juan I.; Doty, Matthew F. American Physical Society (2013)
      We use photoluminescence spectroscopy to investigate the ground state of single self-assembled InGaAs lateral quantum dot molecules. We apply a voltage along the growth direction that allows us to control the total ...

    • openAccess   Hole spin relaxation in InAS/GaAs quantum dot molecules 

      Segarra, Carlos; Climente, Juan I.; Rajadell Viciano, Fernando; Planelles, Josep IOP Publishing Ltd (2015-09)
      We calculate the spin–orbit induced hole spin relaxation between Zeeman sublevels of vertically stacked InAs quantum dots. The widely used Luttinger–Kohn Hamiltonian, which considers coupling of heavy- and light-holes, ...
