Figure 15.

A wide variety of patterned metal nanostructures and 3-D stacks can be fabricated using pattern transfer of thin gold layers from molds followed by cold welding with another gold layer or self-assembled monolayer. The 3-D structure shown in figure (c) is difficult to fabricate by other means. Reprinted with permission of John Wiley & Sons, Inc., Copyright 2004, from (Jeon et al., 2004)
