Condensed Matter Experiment Ⅱ

Surface Physics


Professor : Shozo Suto
Associate Professor : Toyoaki Eguchi


 We are interested in the physics at surfaces, interfaces, nanostructures and other novel low dimensional structures, where electrons behave quite differently from electrons in the bulk. We have three ongoing projects. First, experimental and theoretical study of atomistic process at growth of ordered nanostructures observed with atomic resolution by variable temperature scanning tunneling microscopy (STM) and fast scan STM. Second, experimental and theoretical study of elementary excitations at surfaces and nanostructures. We use high resolution electron energy loss spectroscopy (HREELS) to observe surface phonons and plasmons. In order to correlate the macroscopic information on electronic and vibrational excitations with microscopic structures, we have constructed the combined measurement system of HREELS and STM. Third, we study the diffusion of Born and Phosphorus in a silicon crystal to make a small electronic device as small as 10 nm scale collaborating with a private comany.
