Abstract

This article describes the bond length distribution of the Ga1-xlnxNyAs1-y quaternary alloy which has attracted much attention in recent years for its potential use in fabricating long wavelength optoelectronic devices, and propose a statistical model, which calculates the average bond lengths in as-grown and fully annealed Ga1-xlnxNyAs1-y alloys when constituent proportion is an integer and x:y 4. First we calculate the statistical bond distributions of a definite super cell, and then generalize the formulas of the average lengths after extracting the distributing probabilities of the N–centered nearest-neighbor clusters with a Gaussian distribution based on the former experiment. Finally the optimized bond lengths of Ga28ln4N1As31 super cells under different nearest-neighbor environments are obtained using DMol3 module in Material Studio based on the first principle, and the average bond lengths and strain are computed. We find that the local strain, the total strain and total binding energy of the system will decrease after annealing, which is in good agreement with the previous researches.
