Epitaxial growth of tetracene on the Ag (110) surface
Applied Surface Science xxx(2004)xxx-xxx，-0001，（）：
Thin film growth of tetracene on Ag (110) has been investigated by using scanning tunneling microscopy (STM). In the monolayer regime, the tetracene molecules formed islands of ordered structure, which is commensurate (4-fold periodicity) in the [110] direction, but incommensurate in the [001] azimuth, with the substrate. All the tetracene molecules align regularly with their longer axes parallel to the [001] direction, and with their molecular planes parallel to the surface. At multilayer coverages, the tetracene molecules form a crystalline film in a novel 3D orthorhombic structure, with their orientations remained unchanged. Growth of tetracene on Ag (110) is in the layer-by-layer growth mode.
