Profile

Nanomaterials have inspired many researchers to investigate 0,1 and 2 dimensional quantum confined materials. The majority are grown by a La-Mer type or direction specific growth in which monomers are attached one by one. Recently, oriented attachment is used to growth anisotropic particles in which more complicated crystalline materials can be made. Especially lead chalcogenide quantum dots are used, due to their highly symmetric rock salt crystal structure. This insures six chemically identical {100} crystal facet, which can attach to neighbouring dots while the {111} facets cannot. Using these building blocks, materials can be made having dimensionalities between 0 and 2 in which each quantum dot can be seen as an artificial atom. Attaching these dots together insures strong coupling and yield materials with interesting band structures with an enormously tune ability, due to its ionic nature and small size. What triggers the single dots to grow into certain periodic low dimensional structures is however not completely understood.

My project is about the synthesis and the characteristics (optical and electrical) of these low dimensional semiconductor materials. Until now it is possible to make two types of periodicities; the square and honeycomb structure. These crystalline materials are made by two sequential processes. First, the nanocrystals self-assemble and soon after attachment takes place, called oriented attachment. Other elemental compositions can also be made out of these structures by a process called cation exchange, in which the original lead is exchange to f.e. a cadmium atom. There are a lot of challenges concerning my PhD project for example in the optimization of the formed structures, increase reproducibility of the formed structures and the passivation of the  surfaces to get air stable structures and better electronic performances.
