Study Findings from X.L. Fan et al Broaden Understanding of Low Dimensional Structures

May 13, 2014

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Low Dimensional Structures. According to news reporting originating from Chengdu, People's Republic of China, by VerticalNews correspondents, research stated, "By performing density functional theory calculations, this work clarifies the sites and energetics of both the non-dissociative and dissociated adsorptions of CH3SH on clean Au(1 1 1) and Au(1 1 1) with intrinsic defects. It was found that the adsorption on defect-free Au(1 1 1) is most stable for non-dissociative CH3SH."

Our news editors obtained a quote from the research, "Its direct molecular dissociation to form CH3S/Au and H/Au is barred by an activation barrier of 0.9 eV. However, the presence of neighboring Au-ad can assist the dissociation reaction to form CH3S-AU(ad)-H by lowering the energy barrier to 0.6 eV."

According to the news editors, the research concluded: "As for the dissociated CH3S, the surface geometry of two CH3S joined by a Auad is the most favorable one."
