Abstract
The observation of ordering in GaAsP alloys is reported. The CuPt structure with ordering along the 〈111〉 directions on the anion sublattice was observed by transmission electron diffraction patterns in GaAs1−xPx alloys at compositions of x=0.3 and 0.4. Only two of the four CuPt variants were observed. The degree of ordering along the 1/2[1̄11] direction is higher than for the other variant, ordered along the 1/2[11̄1] direction. In addition, the degree of ordering decreases when x is reduced from 0.4 to 0.3.Keywords
