Search for new electronic properties using the interface structures controlled on nano scales

In this project we have theoretically studied the electronic properties of nanoscale materials that have been recently produced. We focused on the electronic states of their interface structures, and purposed to clarify the electronic properties of new materials and to search their new functions. We have studied the electronic structures and transport properties of twinning superlattice nanowires, GaInP2 twinning interfaces, and the interfaces between topological insulators and metals, and obtained new knowledge about these materials.
