Creating a unification platform for bottom-up and top-down systems is one of the most important issues for harvesting fruits of upcoming nano-technologies and nano-science as well as those of Si-LSI-based information technologies. We have been studying nanostructure physics by preparing systems being discrete in nanoscale but having a bulk size, investigating the electro-optical interactions, electronic correlations, and possible spontaneous symmetry breakdown in such systems. We are interested in both fabricating spiral hetero-structures for a new platform as well as for functional memories plus high efficiency photovoltaic devices and calculating the electronic structures of the systems.

Young students as well as those who are interested in aforementioned research fields are welcome to visit at our Lab. and to have discussions with us.
