Abstract
Dipolar transformations of two-dimensional arrays of quantum dots are investigated theoretically. Homogeneous and non-homogeneous two-dimensional distributions are modeled by considering sections of the quantum dot array with different confinement potential. The dipolar transformations are tested by means of simulation of the dispersion of electrons of a beam traveling parallel to the plane of the quantum dot array. We calculate the electron energy loss function as a function of the temperature for different non-homogeneous distributions, considering several confinement potentials and coupling potentials among the quantum dots. Our results indicate that it would be possible by electron energy loss spectroscopy experiments to detect these dipolar transformations.
