Strings of metal half-shells fabricated using colloidal particle monolayer as a template.
A two-dimensional (2-D) polystyrene (PS) particle monolayer is demonstrated as a template for the fabrication of one-dimensional (1-D) strings of metal shells. Metal is deposited by vacuum evaporation onto the PS particle monolayer, which is tilted at an angle (theta) between the normal of the monolayer plane and the direction of metal deposition. The effects of the metal deposition thickness, the tilt angle (theta) of the particle monolayer, and the type of metal on the formation of 1-D strings of metal shells are investigated. Strings of fan-shaped Au shells are obtained at a given tilt angle and deposition thickness. On the other hand, 1-D strings of Cr and Ag cannot be obtained, and they tend to form 2-D films and half-shell dots of the metal, respectively.
