Nanometer-scale molecular deposition using the surface Plasmon polariton interference field on a metal film

We explore the possibility of using the surface plasmon polariton interference field to deposit neutral molecules onto a silver film perforated with two double-slits. The Monte Carlo simulated results show that the deposited molecular pattern is the periodic line array with a width resolution of ∼10 nm and a period of 530 nm when the molecular beam is well-collimated. Dependences of the deposition resolution on the system parameters, the potential applications and improvements are also discussed in some detail.
