Optimizing thermal management of equipment via FEM-simualtions — •Tristan Stiller — CreaTec, Erligheim, Deutschland

Keeping track of temperatures for any given process is extremely important. Whether it is to accurately estimate evaporation rates of thermal effusion cells, or to gain a better understanding of spatial temperature gradients along a sample, which in turn affects growth conditions. Using COMSOL's simulation capabilities we can simulate Joule heating of filaments, heat transfer in solids, and thermal radiation, which is the main heat transfer mechanism in UHV applications. Two use cases of these simulation results were both the optimization of effusion cell design, as well as improvement in substrate heating; both of which play a crucial role in quantum dot growth or the investigation of the behavior of single atoms in magneto-optical traps, for example.
