Selective Adsorption and Crystalline Film Growth of Picene Molecules on the Pb(111) Surface
The picene molecules grown on a Pb(111) substrate have been investigated by low-temperature scanning tunneling microscopy. Picene molecules present selective adsorption at low coverage due to the quantum size effect of the Pb(111) film. The lattice of picene exhibits chiral switching and lattice rotation induced by the electric field. When increasing the coverage, two crystalline phases, (110)-like and (211̅) phases, have been found in the picene monolayer regime. Our results provide new choices and ideas for preparing new organic electronic devices.
