Studies of growth behavior of tetracene on Ru(101¯0)

Electronic properties and adsorption structures of tetracene on the Ag(110) surface

“…Its aromatic structure is expected to be beneficial for the flat-lying geometry on the metallic surface which maximizes the interaction between the extended π electron of the tetracene molecule and the periodic d electron of the transition metal. The growth behavior of tetracene on single crystal surface have been reported recently, including Cu(110) [14], Ag(111) [15], Si(110) [16] and Ru(10 1 0) [17]. On Ag(110) surfaces, Our previous study showed a partially commensurate multilayer tetracene structure, but the most stable adsorption site was uncertain [18].…”

“…On the other hand, strong interaction between molecule and substrate leads to an amorphous film instead of highly ordered phase. Recently, a long-range ordered monolayer of tetracene on the Cu(110) [14], Ag(111) [15] and Ru(10 1 0) [17] surface have been reported. The flat-lying growth mode of tetracene on Ag(110) [18] have also been demonstrated by using scanning tunneling microscope (STM) and other techniques.…”

Adsorption and diffusion of adatoms on Ru(0001): A first-principles study

“…Further studies would be required to understand atomic processes of nucleation and growth behaviors of various adsorbates on Ru(0 0 0 1), which could alter chemical activation and affect the self-organization progress. Although a lot of attentions were paid to the formation of thin oxide film on Ru(0 0 0 1) surface [2,[7][8][9][10][11][12] and adsorptions of organic molecules on Ru(0 0 0 1) [13,14] due to their important applications in industry, there have been only a few investigations on adsorption of elemental atoms on Ru(0 0 0 1) [15][16][17][18][19][20][21][22][23]. Such systems, however, involve fundamental issues, such as growth mechanism, novel surface electronic structures, and formation of surface alloy/compound.…”
