Observation of atoms and molecules on solid surfaces by a local probe method

Atoms and molecules on solid surface (100-300 K) are observed by means of scanning tunneling microscopy (STM). Current research interests are focused on:
(1) Reconstruction and its dynamical processes on solid surfaces induced by adsorption and reaction of atoms and molecules.
(2) Microscopic states of adsorbed molecules.
(3) Identification/discrimination of adsorbed molecules such as DNA base molecules.
(4) Dynamical processes of surface migration and superstructure formation of adsorbed molecules.
