Surface/Nano Physics
Research Subject
Experimental Research on Properties of Solid Surfaces and Nanoscale Structures
Current Research
Surfaces of materials such as semiconductors, metals, and topological insulators, are platforms of our research where rich physics is expected due to the low-dimensionality and symmetry breakdown. (1) Electronic/spin/mass transports, (2) atomic/electronic structures, (3) phase transitions, (4) electronic excitations, (5) spin states and magnetism, and (6) epitaxial growths of coherent atomic/molecular layers/wires on surfaces, topological surfaces, and nano-scale phases such as surface superstructures, ultra-thin films such as graphene and silicene. We use various kinds of ultrahigh vacuum experimental techniques, electron diffraction, scanning electron microscopy, scanning tunneling microscopy/spectroscopy (STM/S), photoemission spectroscopy, in-situ four-point-probe conductivity measurements with four-tip STM and monolithic micro-four-point probes, and surface magneto-optical Kerr effect measurements.
