Stevens researchers pioneer novel technique to make plasmonic nanogap arrays
Date:9/6/2011

monstrated to create sub wavelength features. Dr. Strauf's team advanced the HL methodology by using four-beam interference and the concept of a compound lattice to create tunable twin motive shapes into a polymer template, resulting in metallic air gaps down to 7 nm, seventy times smaller than the wavelengths of the blue laser light utilized to write the features.

The Stevens scientists extended the utility of HL to create gaps with results comparable to laborious serial fabrication techniques such as electron beam lithography or focused ion beam milling. Besides being a simpler and more cost-effective production method, their technique does not require a clean room and currently achieves 90% uniformity in the array pattern. Therefore, these innovations provide the foundation for making high-quality, large-scale arrays at a greater speed and lower cost than previously realizable.

"This research project provided me with an opportunity to become an expert with the HL technique," says Xi Zhang, the first author of the Nano Letters article and a PhD candidate. Xi and her fellow students are now measuring the surface enhanced Raman scattering (SERS) effects that result from these arrays and continue to improve the uniformity of the arrays during fabrication. "We just got some excellent results from first SERS experiment, and certainly there are more papers to follow up," she says.

Dr. Strauf is Director of the NanoPhotonics Laboratory (NPL) at Stevens, where he oversees cutting-edge research in the fields of solid-state nanophotonics and nanoelectronics. Research at the lab includes the development of fabrication methods for nanoscale materials and quantum device applications. Recent NPL projects have resulted in papers published on quantum dots and graphene. The lab has received project funding from the Air Force Office of Scientific Research and two National Science Foundation instrumentation grants. Dr. Strauf is also the recipient of the p
