摘要：

The extended x-ray-absorption fine-structure technique is applied to study the local atomic structures of liquid GaSb and InSb using an improved sample holding method. The partial pair distribution functions and coordination distributions of the two liquids are given by using reverse Monte Carlo simulation. The coordination numbers in liquid GaSb are mostly 5 and 6, in addition to which there are about 15% of 4 coordination and about 10% of 7 coordination. On average, the coordination number is 5.4. The results are similar in liquid InSb. This structural study provides some hints of the metallic behavior and density increase in the liquid. [S0031-9007(97)04456-6].
