We propose to investigate the role of Li-doping in the two In compounds In2S3 and In2O3. Li-doped In2S3 is of interest as electrode in rechargeable Li-batteries. In2O3 doped with tin (ITO), on the other hand, is the most important optical transparent, conductive film. We want to investigate whether Lidoped In2O3 and In2S3 have similarly interesting materials properties. The first central interest is to determine the maximum amount of incorporated Li and the atomic position(s) of the implanted foreign atom Li which can, for example, be intercalated with high amounts into the spinel ß-In2S3. To determine the microscopic structure we will apply the technique of perturbed angular correlations (PAC). Both compounds are ideal materials for this technique when using radioactive 111In probes, which will be located at their "natural" cation lattice sites. Implantation of the radioactive 111In probes and of stable 7Li for doping will be done at the 500 kV IONAS implanter at Göttingen. In addition we want to trace the Li-atoms by the method of a-emission channeling of 8Li. The necessary nuclear reaction 7Li(d,p)8Li can be done with the newly installed Pelletron accelerator of our institute.

我们建议调查的作用，锂掺杂在两个在化合物In 2S 3和In 2 O3。锂掺杂的硫化铟是锂电池的理想电极材料。另一方面，掺杂有锡的In 2 O3（ITO）是最重要的光学透明导电膜。我们想研究Lidoped In 2 O3和In 2S 3是否具有类似的有趣的材料特性。第一个中心兴趣是确定掺入的Li的最大量和注入的外来原子Li的原子位置，所述外来原子Li例如可以以高量插入到尖晶石Al 2 O3-In 2S 3中。为了确定微观结构，我们将应用扰动角相关（PAC）技术。当使用放射性111 In探针时，这两种化合物都是这种技术的理想材料，这些探针将位于它们的“天然”阳离子晶格位置。放射性111 In探针和稳定的7 Li掺杂将在哥廷根的500 kV IONAS加速器上进行。此外，我们还想用~ 8Li的α发射沟道方法来追踪Li原子。用我所新安装的Pelletron加速器可以进行必要的核反应7 Li（d，p）8Li。
