Abstract
An introduction to crystal growth with the Bridgman-Stockbarger technique and physical characterization of single crystals.
Learning objective
The practical laboratory course gives an insight into the growth of single crystals and their applications. Focus lies on the growth of semiconductor crystals and the measurement of their physical (optical & electronic) properties. The complete work is documented in a detailed scientific report.
Content
The growth of perovskite (CsPbBr3) semiconductor crystals using the Bridgman-Stockbarger technique as a model system for single crystals grown from the melt. 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, and photodetection.
Lecture notes
Electronic version of the script will be provided.
