Abstract

We study the adsorption of the amino acid cysteine on the Au(110) surface by means of density functional theory. Different adsorbate-substrate geometries are investigated regarding geometry, adsorption energy, and changes in the density of states. In particular we compare flat versus upright adsorption configurations in which the molecule registers to the surface via a deprotonized thiolate head group and eventually the amino side group. Sulfur-gold and amino-gold bonding geometries are discussed with their implications for electronic properties.
