Abstract:
1. An apparatus for performing spectroscopy, the apparatus comprising: a substrate having a surface; a plurality of surface-enhanced spectroscopy (SES) elements positioned substantially along a first plane on the surface of the substrate; a first electrode positioned adjacent to the plurality of SES elements substantially along the first plane; a second electrode positioned adjacent to the plurality of SES elements substantially along the first plane and on a side of the plurality of SES elements that is opposite the first electrode, wherein the first electrode and the second electrode are to generate an electric field around the plurality of SES elements when voltages are applied through the first electrode and the second electrode; and a third electrode positioned beneath the plurality of SES elements, wherein the first electrode and the second electrode are to have a common bias and the third electrode is to have a bias that is opposite the common bias.
