A short-range ordered structure of a semiconductor laser material Gao.5Ino.5P was investigated by high-resolution electron microscopy together with electron diffraction. A high-resolution electron microscope image of Ga0.5In0.5P was processed to visualize a short-range ordered atomic arrangement. A model of the short-range ordered structure was obtained by assuming the proportionality between the brightness of white dots in the image and the concentration of In in atomic columns parallel to the incident electron beam. Based on the structure model, diffuse scattering intensity was calculated and it was compared with the observed diffraction pattern.
