dc.description.abstractIn this work, the effects of spatial electric field and ratios of dot edge lengths (L-z/L) on the binding energy and polarization of a donor impurity in TQD are presented. Calculations are performed within the effective-mass approximation using the variational procedure and considering an infinite confining potential on all surfaces of the system. The binding energy and polarization are calculated as a function of (L-z/L) ratio. It is found that binding energy and polarization of a donor impurity in TQD depend strongly on the L-z/L ratio, applied spatial electric field strength and impurity position. (c) 2012 Elsevier Ltd.
