Бібліографічні посилання Google АкадеміяNear-field manipulation in plasmonic nanocavities can provide various applications in nanoscale science and technology. In particular, a gap plasmon in a scanning tunneling microscope STM junction is of key interest to nanoscale imaging and spectroscopy. Here we show that spectral features of a plasmonic STM junction can be manipulated by nanofabrication of Au tips using focused ion beam. Our approach paves the way for near-field imaging and spectroscopy with a high degree of accuracy. Manipulation of near-field properties, such as a spectral response, optical coupling to far fields, and local field enhancement, by using metallic nanostructures is a foundation of plasmonics, providing a wide range of applications in nanooptics, 1 single-molecule sensing, 2 and enhancement of photovoltaics, 3 and photochemistry.

The Fourier spectra exhibit a single peak but higher-order peaks are absent, indicating a significant decay loss of the SPPs due to damping into the metal as well as coupling to far-field radiation at the apex and the groove.

In physics , a plasmon is a quantum of plasma oscillation. Just as light an optical oscillation consists of photons , the plasma oscillation consists of plasmons. The plasmon can be considered as a quasiparticle since it arises from the quantization of plasma oscillations, just like phonons are quantizations of mechanical vibrations. Thus, plasmons are collective a discrete number oscillations of the free electron gas density. For example, at optical frequencies, plasmons can couple with a photon to create another quasiparticle called a plasmon polariton.

The subject material is well organized, with abundant references to the primary literature, plasmonics poasmonics the potential to confine and guide light below the diffraction limit and promises a new generation of highly miniaturized photonic devices. Considered one of the major fields of photonics of the beginning 21 st century. Open access peer-reviewed 6. A soliplasmon resonance is on the other hand considered as a quasiparticle combining the surface plasmon mode with spatial soliton as a result of a resonant interaction.
