Mercury iodide nucleation and crystal growth in vapor phase (4-IML-1)

摘要

The objectives of this experiment are to grow simultaneously three single crystals of mercuric iodide (HgI2) in an imposed temperature profile and to assess the advantages of growth in microgravity on the HgI2 crystal quality. Growth in microgravity should reduce fluctuations in HgI2 concentrations and thus decrease the resultant crystal defects. In order to test this hypothesis, a seeded growth of HgI2 crystals will be performed on International Microgravity Lab. (IML-1).
