In collaboration with the National Institute of Advanced Industrial Science and Technology (AIST), our laboratory utilizes a variety of techniques to design new materials for various electronics applications. These techniques include first-principles calculations of material properties, which only require the positions and types of atoms as input. In addition to first-principles calculations, we also use machine learning techniques to identify promising candidate materials for new electronic applications. The most promising candidate materials are then fabricated and investigated experimentally in collaboration with AIST. As many of these materials are amorphous (solids with a liquid-like internal structure), we investigate their physical and electronic structures through measurements using synchrotron radiation. Synchrotron radiation-based techniques include X-ray absorption spectroscopy, where the atoms in the material act as both the probe and the detector, allowing the local structure to be obtained.
