Research Interests

Dr. Katsumi NAGAOKA's research interests lie in exploring the local electronic, magnetic, and mechanical properties of atomic and molecular structures at surfaces. He is interested in studying how local interactions between atomic-scale structures affect their microscopic behavior, and how quantum mechanical effects might influence nano-device behavior in very small structures. His main experimental tool is scanning tunneling microscopy (STM), which he uses in combination with other experimental tools to both fabricate atomic-scale structures and probe them spectroscopically. His recent research target focuses in microscopic understanding of the interaction of spin-currents with structural and magnetic inhomogeneities at the nano-scale, such as heterostructure interfaces and magnetic domain walls. In order to realize cutting-edge experiments of spin-dependent transport in nano-scale and molecular systems, he has been spending instrumental development of a spin-sensitive multi-probe STM system.
