| Research Abstract |
Alanine molecule on Cu(001) is bonded to three Cu atoms through the two oxygen atoms of carboxylate group and the nitrogen atom of amino group. The ordered structure accompanying a dislocation of substrate Cu atoms is determined by I-V curves in LEED observation. In the adsorption of racemic mixtures, D- and L-alanine molecules segregate to form their own c(2x4) domains, thus creating the boundary lines along the [110] direction. The intermolecular network between the boundary is characterized by TPD profile due to a difference in hydrogen bonds between the hydrogen atoms of the amino group and the oxygen atom of the carboxylate group. In adsorption of L-serine with hydroxy group instead of a hydrogen atom in methyl group of alanine, a few different ordered overlayer structures are formed by addition of hydrogen bonds between the hydroxy groups.
