AbstractAn introduction to single crystal growth with the Bridgman-Stockbarger technique and thin film preparation using melt processing and evaporation deposition. Physical characterization of single crystals and thin films.
ObjectiveThe practical laboratory course gives an insight into the growth of single crystals and their applications. Focus lies on the growth of semiconductor crystals, thin film preparation (melt & evaporation technique) of semiconducting materials and the measurement of their physical (optical & electronic) properties. Additionally, the complete work is documented in a detailed scientific report.
ContentThe growth of perovskite (CsPbBr3) semiconductor crystals using the Bridgman-Stockbarger technique as a model system for single crystals grown from the melt. Alternatively thin films derived over melt processing or via evaporation deposition are prepared. The preparation of crystals for physical measurements through cutting and polishing. Measuring optical characteristics (absorption) as well as electronic properties, including current-voltage (IV) measurements, time-of-flight, charge carrier recombination, charge extraction efficiencies, noise measurement and photodetection.
