  • A microscopic model for the dielectric function of Ge quantum wires 
    Alfaro, P.; Vazquez, R.; Lobota, I.; Ramos, A.E.; Cruz-Irisson, M. (Functional Materials, 2005)
    Free-standing, infinitely long, and homogeneous quantum wires of square cross section are considered using the chessboard-like supercell model. The optical transition properties of Ge nanocrystals are studied by means of ...
  • Quantum confinement effects in Ge nanocrystals 
    Miranda, A.; Ramos, A.E.; Nino de Rivera, L.; Cruz-Irisson, M. (Functional Materials, 2005)
    The exciton Bohr radius of bulk Ge is larger than that of Si, hence resulting more prominent quantum size effects. In this work, the electron structure of Ge nanocrystals is studied by means a sp³s* tight binding approximation. ...
