摘要：
The bond lengths for the GexSi1-x alloys are calculated in the empirical tight-binding force model with using a zincblend-like unit cell to simulate the GexSi1-x alloys. The results agree with the experiments quite well, showing that the bond lengths are independent on the alloy composition and close to the Pauling's limit. The failure of the valence force field model in calculating the bond lengths for GexSi1-x alloys is discussed.
