Optical functional material engineering course

The information society and optical information technology are supported by semiconductor and optical electronics. Research in this course is conducted on creation of new optical/electronic materials and association of the structure and the physicality targeting at a wide range of materials from crystal materials to non-crystal materials.

Crystal Physics and Engineering Laboratory

[Keywords] Advanced transmission/scanning electron microscopy, crystal orientation analysis, electron diffraction, 3D tomography, shape memory alloy, permanent magnet, magnetic material, semiconductor thin film, heat resistant alloy, intermetallic compounds

[Research outline] In research and development of the functional materials, it is important to control microstructure in an atomic level to get novel and superior material characteristics according to the social needs. Our laboratory conducts research from fundamental aspects of phase transformation in alloys to extensive studies on microstructure analysis of functional materials such as high-performance magnets and heat resistant alloys using advanced transmission/scanning electron microscopy.

Inorganic Optoelectronic Materials Engineering

[Keywords] thermoelectric materials, oxide thermoelectric devices, oxide semiconductors, energy conversion materials, photocatalysts, electronically conducting ceramics, thermal conductivity, nanostructure control, low-dimensional nanomaterials, self-assembly, integrated quantum structures, molecular assembly, organic-inorganic composites, functional inorganic materials

[Research outline] This laboratory, led by Prof. Michitaka Ohtaki, was newly established in 2013 focusing on development of energy-oriented novel functional materials based on inorganic materials science, chemistry, and physics. It also aims at more comprehensive targets in materials science by combining a wide variety of the properties of inorganic materials with intelligence of organic molecules. The most distinguished achievement of our lab is a pioneering work on oxide thermoelectric materials resulting in our continuing accomplishments on the best performances of both n- and p-type bulk thermoelectric oxides so far. Our perspective, however, is not limited to the thermoelectric materials, but extends to unconventional approaches in materials science for next-generation materials including low-dimensional quantum-structured inorganic nanomaterials spontaneously formed by self-assembly molecular templating.
