A simple route to the fabrication of 3-D structure on nanofilm

A diversity surface energy inspired 3-D insulator/metal(IM) structures, which fabricated on a independent Au nanofilm (the menbrane thichness is 50nm and the size is 3 ×3 centimeters) composes of 5.625e7 units. The diameter and the thickness of every units are ~3um and 50nm respectively. In this report, the novel method for the fabrication of 3-D structures on the nanofilm, base on the high surface energy material removal of the underside of the hole and the good malleable material compensation the stress concenstration of the top surface. A low turn turn on voltage of 2V/μm is estimated for IM micro-structures.
