Vibrational Imaging at the Nanoscale: Surpassing the Diffraction Limit Using Tip-Enhanced Raman Spectroscopy
… offer molecular information such as vibrational spectroscopy techniques that allow one to collect molecular or lattice vibrations yielding to a precise picture of the molecular interactions in bulk materials as well as in surfaces and interfaces. Unfortunately optical spectroscopy techniques are …

Development of a multipurpose near-field imaging platform
… techniques has been revolutionizing for multiple fields - Condensed Matter Physics, Material Science, Chemistry, and Biology. This high potential is met with the special requirements of sub-nanometer SPM, and the resulting instrument is usually sophisticated, expensive, and requires …

Optical and Plasmonic Properties of Metallic Tip /Surface Junctions
… frequencies. Introducing a nanopraticle or a tip to an infinite metallic surface breaks the continuity of the surface allowing coupling with light. This leads to remarkable nearfield focusing and enhancement at optical resonances through the gap between the metallic nanoparticle/tip and the …

Excitation, Interaction, and Scattering of Localized and Propagating Surface Polaritons
… investigated by means of the semianalytical multiple-multipole (MMP) method. The results are compared to experiments. In the first part, the surface plasmon resonance (SPR) of metal nanoparticles is analyzed. This resonant collective oscillation of the free electrons in a metallic nanoparticle …
