Registration only until 27.01.2020. Participants who have passed the course "Inorganic Chemistry II" will be favoured. Other students can only be admitted if spaces are available. Limited to 20 participants. Electronic registration is mandatory (except for ETH-external participants).
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.
Performance assessment
Performance assessment information (valid until the course unit is held again)
Repetition only possible after re-enrolling for the course unit.
Additional information on mode of examination
Participants are graded according to: 1. Laboratory skills & performance, 2. Report. Both parts are graded separately and weighted equally, and the final grade will be the average of these grades. Detailed information on the requirements will be given at the beginning of the laboratory course by the assistants and are given in the script.
