Method for producing semiconductor microparticles and the microparticles

摘要

It is an object to provide a method for producing compound semiconductor particles in which monodisperse compound semiconductor particles can be prepared according to the intended object, clogging with products does not occur due to self-dischargeability, a large pressure is not necessary, and productivity is high. In producing compound semiconductor particles by separating and precipitating, in a fluid, semiconductor raw materials, the fluid is formed into a thin film fluid between two processing surfaces arranged so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the semiconductor raw materials are separated and precipitated in the thin film fluid. Further, in producing semiconductor microparticles containing semiconductor elements by reacting a compound containing semiconductor elements, in a fluid, with a reducing agent, the fluid is formed into a thin film fluid between two processing surfaces arranged so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the compound containing semiconductor elements is reacted with the reducing agent in the thin film fluid.
