GHF炉による半導体混晶育成

We are preparing for crystal growth experiments in microgravity using Gradient Heating Furnace (GHF). The one-dimensional Traveling Liquidus-Zone (TLZ) growth model is limited by the radial temperature gradient, convection in a melt and so on. Such factors affecting one-dimensionality are studied experimentally and theoretically. Reaction between the melt and cartridge materials is being investigated for analyzing safety requirements and for designing flight cartridges. Here, achievements in the present preparatory stage are reported.
