Abstract Scope |
Optical floating-zone (OFZ) furnace has gained attention recently owing to its potential in producing single crystals of complex materials. However, difficulty in monitoring the temperature within the furnace and the sample, as well as the lack of knowledge about physical parameters related to the growth technique, impose critical barrier to study this process quantitatively. Here, we apply a heat transfer model informed by experiment and machine learning to understand the temperature distribution within a sample processed in a mini OFZ furnace. The model is used to predict sample temperature in various gas environments and experimental setups for potential sample materials. We demonstrate that temperature distribution in the sample, which directly affects the outcome of the crystal growth process, can be predicted by models parameterized by a limited number of synchrotron experiments. The simulations can therefore be used to correlate the temperature distribution and crystal growth results from less expensive experiments. |
