        Summary
        Oriented attachment offers new possibilities to precisely build up complex structures. In this thesis oriented attachment of PbTe and PbS is investigated on an ethylene glycol toluene/hexane interface. While drying a quantum dot solution on a layer of ethylene glycol, the quantum dots attach in three distinct superstructures. Linear attachment is observed for both materials in which the quantum dots attach head to head. Also totally square structures are formed for PbS and a more parallelogram shape for PbTe are observed. For PbTe also patches of siliceen lattices are fabricated. Models were made, to explain how these different structures create
