Abstract
The purpose of “Alloy Semiconductor” experiment is to make clear the factors for crystal growth of a high-quality bulk alloy semiconductor by investigating (1) solute transport in liquid and (2) surface orientation dependence of growth kinetics under microgravity and terrestrial conditions. The temperature gradient furnace onboard “Kibo” is used for the growth of an InxGa1-xSb bulk crystal which is a potential substrate material of optoelectronic devices such as thermo-photo-voltaic cells and gas sensors, since the bang gap and the lattice constant of the crystals are tuned by adjusting the composition. The space experiment is briefly summarized in view of the past history from preparation for the flight.
