dc.description.abstract | The formation and surface structures of cyclohexanethiolate (CYH-S) and cyclohexaneselenolate (CYH-Se) self assembled monolayers (SAMs) on Au(1 1 1) were probed to understand headgroup effects on the formation of SAMs with an alicyclic backbone using scanning tunneling microscopy (STM). CYH-S SAMs on Au(1 1 1) formed via solution deposition at room temperature (RT) were composed of small ordered domains with sizes ranging from 10 to 30 nm, whereas CYH-Se SAMs on Au(1 1 1) usually had a disordered phase. The molecular arrangements of CYH-S SAMs on Au(1 1 1) could be described as a (5 x 2 root 3)R30 degrees structure. CYH-Se SAMs formed via vapor deposition at RT had a long-range ordered phase (greater than 100 nm) including missing rows and molecular defects. A highly ordered crystalline phase of CYH-Se SAMs on Au(1 1 1) with fewer structural defects was formed at 323 K for 12 h that was assigned to a (root 3.5 x 2 root 10)R27 degrees structure. STM observations revealed that the domain formation and surface structures of CYH-Se SAMs on Au(1 1 1) were completely different from those of CYH-S SAMs. Furthermore, we found that CYH-S and CYH-Se SAM can be utilized for bonding-induced work function modification of Au substrate through Kelvin probe force microscopy measurement. | - |
