Hierarchy Control in Structure and Creation of Novel Properties in Nano Scale Materials
update：2020-06-16
Features
Crystals produced from the building blocks using a concept of geometrical materials, from the ubiquitous elements such as B, C, N, O, Si, Ge and 3-d elements show the following characteristics:(1) Special properties resulting from the bonding nature and geometrical symmery.
(2) New properties expected from confinement and interface.
(3) A variety of phonons as phonon engineering.
(4) Interplay among phonons, itinerant electrons and magnons.
Materials are synthesized using the strategy of natural aboundant ubiquitous elements for safety. Novel properties can be expected for advanced electronic devices. The structure of new materials can accurately be determined by various experimental techniques.
Targeted Application(s)/Industry
New materials produced by employing a new concept beyond the conventional methods can promote a new materials science for future electronics. Our research covers nano materials consisting of organic to innorganic elements. Thermoelectric materials for energy conversion and high mobility materials via Dirac quantum statse will be avialable for future electronic materials.Researchers
