Claim Text:
1. A method of densifying a nanostructure array, comprising the steps of: providing a nanostructure device that includes a substrate having a planar surface and an array of nanostructures each extending away from the substrate to a distal end located above the substrate; and moving a contact element relative to the array such that it the contact element initially contacts makes direct contact with at least some of the nanostructures at a location above the substrate surface and below the distal end of the nanostructures and re-orients the nanostructures into at least partial alignment with the substrate surface, wherein the nanostructures remain on the substrate during re-orientation and the contact element comprises a cylindrical roller, and wherein the moving step further comprises rolling the roller across the nanostructures while permitting slip where the roller contacts the nanostructures.
