Abstract

The nature of Bi in molten Bi-Biia mixtures and In in molten In-Inia mixtures is surveyed on the basis of static properties and macroscopic transport coefficient (phase diagram and d.c. conductivity). It is shown that information at the microscopic level due to techniques of pulsed neutron scattering, Raman scattering and NMR can account for their nature. From pulsed neutron scattering data preferred Bi-Bi pair-correlation or polybismuth species is proposed for Bi..It-z melts even at the I-rich side below about 40 at% Bi. The localized electronic states around the Fermi level may be established and conduction takes place via hopping of electrons from one trapping site to another for these solutions. The strong concentrationdependence of the first peak distance, which is related to preferred Bi-Bi distance and observed over the range of 0.4

熔融Bi- bii3混合物中的Bi和熔融in - ini3混合物中的in的性质

根据静态性质和宏观输运系数(相图和直流电导率)考察了熔融Bi- biia混合物中的Bi和熔融in - inia混合物中的in的性质。结果表明，脉冲中子散射、拉曼散射和核磁共振技术在微观水平上的信息可以解释它们的性质。根据脉冲中子散射数据，提出了优选Bi-Bi对相关或多铋物质。在% Bi下，它-z甚至在富i的一侧熔化。在这些溶液中，可以建立费米能级附近的局域电子态，并通过电子从一个捕获点跳到另一个捕获点来发生传导。在0.4
