利用结构分析数据，确定了超离子导体α-AgI的波数依赖的静态介电函数。介电函数表明存在静电荷密度波，它反映了碘亚晶格。为了比较，还测定了β相和熔融相的介电函数。我们已经发现，在熔融相的介电函数类似于强耦合的单组分等离子体附近的流固转变。
The wave-number-dependent static dielectric function of the superionic conductor α-AgI is determined by use of structural-analysis data. The dieectric function indicates the existence of a static charge-density wave, which reflects the iodine sublattice. The dielectric functions of the β phase and the molten phase are also determined for comparison. We have found that the dielectric function in the molten phase resembles that of the strongly coupled one-component plasma near its fluid-solid transition.
