We study theoretically the electronic properties of the artificial quantumdot honeycomb lattice defined in a two-dimensional electron gas, focusing onthe possibility of achieving a regime in which electronic correlations play adominant role. At first we establish a non-interacting model compatible withrecently studied experimentally devices. According to the values of theobtained electron-electron interaction integrals, we postulate that theinclusion of inherent electron-gas self-screening is indispensable toreconstruct the experimental observations. Applying the Thomas-Fermi type ofscreening, we show that the radius of the anti-dot is crucial to achieve acorrelated state in which phenomena like antiferromagentic ordering andinteraction-induced insulating state appear. We estimate the conditions forwhich the electronically correlated state in an artificial honeycomb latticecan be realized.
