测定了玻璃态as2se3的结构因子对温度的依赖性。在第一个峰上发现了令人惊讶的结果，从40 K到玻璃化转变温度T g，强度大幅增加；相反，第二个峰在这个范围内减小。第一个峰对应于玻璃中的层间相关。它的增加表明了层的平滑，这可能导致层之间的滑动，从而降低了T g以上的粘度。
The temperature dependence of the structure factor of glassy As 2 Se 3 has been measured. Surprising results were found for the first peak, which shows a large increase in intensity from 40 K to the glass transition temperature, T g; in contrast the second peak decreases in this range. The first peak corresponds to interlayer correlation in the glass. Its increase indicates a smoothing of the layers which may lead to layers slipping past one another, thus decreasing the viscosity above T g.
