Influence of step faceting on the enantiospecific decomposition of aspartic acid on chiral Cu surfaces vicinal to Cu{111}

Abstract

On surfaces vicinal to Cu{111}, L-aspartic acid (L-Asp) adsorption causes steps to facet enantiospecifically into {310}^R and {320}^S steps. L-Asp has its highest heat of adsortion on surfaces that naturally expose the {310}^R or {320}^S steps but decomposes preferentially on the {310}^R steps.
