Özet

The modeling of the quantum Hall based quasi-particle interferometers are studied at the quantum dots. The spatial distribution of edge states (ESs) are investigated at filling factor υ=1/3. The electron and potential distributions are obtained by a self-consistent calculation solving Poisson equation within Thomas-Fermi approximation. The ESs are considered as monochromatic beams that carry quasi-particles without scattering. The interference conditions at the Laughlin quasi-particle interferometers are investigated at the gate defined and etched defined samples.
