A NANOGAP DEVICE FOR FIELD ENHANCEMENT AND A SYSTEM FOR NANOPARTICLE DETECTION USING THE SAME

摘要

A nanogap device for field enhancement is described, which includes: a film made of an electrically conductive material; and a nanogap formed on the film and having a gap-width between a Thomas-Fermi screening length and a skin depth, the Thomas-Fermi screening length and the skin depth being determined by an electromagnetic wave and the electrically conductive material, and system for nanoparticle detection using the device.
