Summary: A new method for fabricating large-area metal and semiconductor nanobridge arrays is proposed in this article, which combines the possibilities offered by nanotransfer printing and UV lithography. The method involves imprinting an array of nanostrips into a resist layer and subsequent UV exposure through an additional mask to define the regions where suspended nanostrip bridges will be formed. Using this method, large-area arrays of Au and Ti/Au nanobridge, as well as SiGe nanobridge arrays, were successfully fabricated. The proposed method is simple, low-cost, and can be implemented on solid and polymer substrates.

Summary: Nanoarchitected materials, with nanoscale features, exhibit unconventional properties such as ultralow density and high energy absorption. However, there is a lack of fabrication methods for producing these materials in a scalable manner. A new technique using holographic lithography with laser exposure is presented, allowing for the manufacturing of nanoarchitected materials with impact resistant capabilities. Experimental results demonstrate the potential of this method by producing nanoarchitected sheets with specific inelastic energy dissipation comparable to other high impact energy absorbing composites and nanomaterials.
