Abstract
The invention relates to a method for the synthesis of a semiconductor compound comprising at least one element of column III of the periodic table of Mendeleev, and an element of column V having a vapor pressure higher than that of element(s) III at the synthesis temperature of the said compound, and according to which, in a closed space, a liquid mass of element(s) III, placed in a first zone of said space which is heated at relatively high temperatures and is contacted with vapors obtained by evaporation of element V, said element V being placed in a second zone of the said space in a non-gaseous form, the evaporation temperature of element V being higher than that of the coldest point provided in a third zone of the said space, and the said first zone being situated between the second and the third zone.
