报告摘要 |
Nanoimprint lithography (NIL) is a cost-effective nano-patterning technology based on the mechanical deformation of a resist. We have demonstrated high-resolution patterning down to 4 nm half-pitch, 3-D patterning of high-aspect-ratio nanostructures and patterning on non-flat substrate. NIL has been used as the enabling technology for nano-science and nano-technology research. I will give three examples. In nano-electronics, I will present our work on crossbar circuits, especially crossbar memory circuits based on transition metal oxide (i.e. memristor) . In nano-photonics, I would like to share is optical meta-materials at near-IR range. In chemical sensing, I will talk about surface enhanced Raman spectroscopy (SERS) sensor fabricated using 3-D NIL.
Bibliography of Prof. Wei Wu
Wei Wu graduated from Peking University with a BS in Physics in 1996, and received a Ph.D. in Electrical Engineering from Princeton University in 2003. He joined the Ming Hsieh Department of Electrical Engineering at the University of Southern California as an associate Professor January, 2012. Before joining USC, he had worked at HP labs since 2003, and he was a senior scientist at nano-electronics research group (formerly known as quantum science research). His work includes the first nanoimprint-fabricated optical negative index meta-material at 1.55 micron range, the first optical modulation using negative index meta-material at near-IR, the first third harmonic generation using meta-material, crossbar memory (i.e. memristor) and logic circuits with the record high densities, highly sensitive surface enhanced Raman sensors fabricated using 3-D nanoimprint, the first room-temperature working single electron memory and the first large area bit-patterned magnetic media fabricated using nanoimprint. The nanoimprint machine he invented has been commercialized via IP licensing. He coauthored 77 peer reviewed journal papers and more than 60 conference presentations, including 12 keynote and invited presentations. He has 54 granted US patents (some of them are grant out of US too) and 63 pending applications. He is senior member of IEEE and editor of Applied Physics A.
