N2 - The use of computer simulation to study laterally coupled quantum dot (LCQD) circuit with integrated quantum point contact for charge read-out was described. The self consistently three-dimensional (3D) Poisson and Kohn-Sham equations within the local spin density approximation was solved to obtain electron density inside the LCQD. Eigenergy spectra and electronic states reflecting the particular LCQD confinement were obtained as a function of the external gate biases. The results show that the constrictions with dented designs give more sensitive detectors than conventional QPC geometries.
