• openAccess   Valence band mixing of cubic GaN/AlN quantum dots 

      Segarra, Carlos; Climente, Juan I.; Planelles, Josep Institute of Physics (2012)
      We study the spin purity of the hole ground state in nearly axially symmetric GaN/AlN quantum dots (QDs). To this end, we develop a six-band Burt-Foreman Hamiltonian describing the valence band structure of zinc-blende ...
