The metallic oxide is one of the functionality materials that can be applied to a lot of fields such as catalyst, optics, magnetic materials, and semiconductor devices. To understand its property in an atomic level is indispensable to develop the next generation technology. Chemical reactions acting on its surface, however, are very complex because it depends on the environment like the temperature and pressure. By developing a non-contact atomic force microscope that has a capability of temperature and pressure control, we have tried to clarify atomic structures, electronic states and reactive process on surfaces of metal-oxide insulators.

金属氧化物是一种功能性材料，可应用于催化剂、光学、磁性材料和半导体器件等许多领域。在原子水平上理解其性质是发展下一代技术的必要条件。然而，作用于其表面的化学反应非常复杂，因为它取决于温度和压力等环境。通过研制一种具有温度和压力控制能力的非接触式原子力显微镜，我们试图阐明金属氧化物绝缘体表面的原子结构、电子态和反应过程。
