Strategic state-of-the-art solid state chemistry for new functional materials Exploring for new multi-functional materials

我们将最先进的战略概念引入固态化学，并寻求新的功能材料和新的功能现象。在我们的研究项目中，我们发现了新的材料，如氧化材料表现出大的负热膨胀和新的现象，如硅的大磁阻。我们还利用同步x射线和高分辨率电子显微镜技术分析了材料的纳米结构，并通过第一性原理计算计算了电子结构，揭示了新功能特性的机制。在我们的研究中开发的材料将对未来的信息技术社会有用。

We introduced a strategic state-of-the-art concept into our solid state chemistry and sought new functional materials and new functional phenonena. During our research project, we found new materials such as oxide materials showing large negative thermal expansion and new phenomena like large magnetoresistance in silicon. We also revealed the mechanisms of new functional properties by analyzing the nano-size structures of the materials with synchrotron X-ray and high-resolution electron microscopy techniques, and by calculating electronic structures from the first principle calculations. The materials developed in our study will be useful for future information-technology society.
