用同步辐射X射线衍射仪和多砧装置研究了液态GaSb在10.1GPa压力下的结构。随着压力增加至约5 GPa，成对分布函数g（r）中的第二和第三峰值显着向较小的r值移动，而第一峰值向较大的r值移动。这表明液态GaSb的结构不均匀收缩。对应于第一峰的移动，配位数增加。这些结果表明，在压力下，在液体GaSb的局部结构转变成一个更高的协调状态。
The structure of liquid GaSb has been investigated up to 10.1 GPa by means of energy-dispersive x-ray diffraction using a synchrotron radiation source and a multi-anvil apparatus. With increasing pressure up to about 5 GPa, the second and third peaks in the pair distribution functions, g(r), shift remarkably toward smaller r-values, while the first peak shifts toward larger r-values. This shows that the structure of liquid GaSb does not contract uniformly. Corresponding to the shift of the first peak, the coordination number increases. These results show that the local structure in liquid GaSb changes into a more highly coordinated state under pressure.
