GROWTH OF In-Sb FINE PARTICLES BY FLOWING-GAS EVAPORATION TECHNIQUE

Fine particles of the In-Sb system were prepared by the FGE technique (flowing-gas evaporation technique). The characteristic of the technique is that the formation of the vapor zone and particle growth zone along the flow of inert gas can be controlled by the inert-gas species and the flow velocity. From single-source evaporations, In fine islands grown on the amorphous carbon in the metal vapor zone showed a fiber structure with [111] and [001] fiber axes. In the particle growth zone In fine particles were formed, showing very frequently a characteristic contrast in them due to a lattice defect. Sb fine particles showed amorphous structure. These results may be attributed to the enhanced quenching effect of the FGE technique, already observed in the ordinary gas-evaporation technique. By coevaporation of In and Sb, granular film grew in the metal vapor zone, and fine particles were formed in the particle growth zone. The crystal structure was assigned to be the zincblende type including the wurtzite type of intermetallic compound InSb.
