We have measured the electronic transport properties of the coupled quantum dot devices at low temperatures. The interplay between the strong many body spin interaction and the molecular states are probed in linear and non-linear transport regime. We observe the formation of strong coherent molecular states clearly visible in the double dot conductance phase diagram. In our study, the spin configuration in multiply coupled quantum dots could be identified using Kondo phenomenon. In addition, the characteristics of the spin dependent molecular states and phase dependant tunneling have been also observed using non-linear conductance measurement of the double dots. The results suggest the importance of the diverse spin related physical issues in artificial quantum dot devices.

Gap Structure

Quantum dots (QDs) of Cds, PbS, and InSb semiconductors in a multi-grain layer of planar-edge microstructure were studied. A model of the ordered arrangement of CT in the micro-gap structure and the flow of current along the lines of parallel arrangement of QD is proposed. Electronic transport at low voltage values (less than 8 V) is determined by thermal and tunnel emission from the QD into the gap, at high values - by the charge restriction in the QD according to the Coulomb block model. A strong influence of IR and UV radiation on the VAC was found.
