| Research Abstract |
In this study, aiming at control of low-dimensional electronic states realized in an interface between self-assembled organic molecular monolayer and metal substrate by molecular modification, we performed STM study of amino-acid molecules adsorbed on Cu surfaces. As a result in β-alanine/Cu(100), we found that novel two dimensional electronic gas states, which have a different dispersion relationship from glycine/Cu(100), were formed. In addition, in glycin/Cu(111), the surface states of the Cu(111) were confined by self-assembled glycine supra-molecular ring structure and quantum corral states were formed.
