Abstract
A method comprising providing an electrically conductive film comprising a first set of electrically conductive nanostructures in a first region that exhibits a first conductivity and a second set of electrically conductive nanostructures in a second region that exhibits a second conductivity, and irradiating the first region of the electrically conductive film with a polarized laser beam having an ultraviolet light frequency at a pulse duration less than 100 nanoseconds, so that, after irradiating the first region of the electrically conductive film, the first region exhibits a third conductivity that is less than the second conductivity.
