  9. Nanoscale Spectroscopy and Plasmonics in Infrared

    09 Mar 2012 | | Contributor(s):: Mikhail Belkin

    In this talk, I will present the results of two of our research projects. I will start with a simple technique for nanoscale mid-infrared spectroscopy that we have developed recently. Subwavelength resolution is achieved by detecting optical absorption through measuring local photothermal...

  10. Peanuts vs. Pyramids: Two Perspectives on MEMS

    23 Nov 2009 | | Contributor(s):: Stephen D. Senturia

    MEMS, the acronym for Micro-electromechanical Systems, also known simply as “Micro-systems,” come in two main types: commodity products (the peanuts) and MEMS-enabled products (the pyramids, or, more correctly, the inverted pyramids). The economics of scale greatly affect how these two classes of...
