چکیده
We present experimental and theoretical results of the molecular sensing performance a novel platform based on magnetic modulation surface-enhanced infrared absorption spectroscopy. For this, we study effect that vibrations PMMA layer have optical magneto-refractive response spintronic antennas. Specifically, periodic array rods is fabricated from giant-magneto-resistance Au/Ni81Fe19 metallic multilayers, depositing top investigated both points view. find relative changes induced by signal are larger than transmission.

Novel surface vibrational spectroscopy: infrared-infrared-visible sum-frequency generation.
A novel type of surface vibrational sum-frequency generation spectroscopy is presented that enables a highly specific measurement of the coupling of molecules on surfaces. With this doubly vibrationally resonant technique, two-dimensional vibrational spectroscopy of molecules on surfaces becomes possible. The technique is demonstrated for the C-O stretch vibration of CO on a ruthenium (001) sur...
متن کاملVibrational ladder-climbing in surface-enhanced, ultrafast infrared spectroscopy.
In a recent work (J. Phys. Chem. C 2016, 120, 3350-3359), we have introduced the concept of surface-enhanced, two-dimensional attenuated total reflectance (2D ATR IR) spectroscopy with modest enhancement factors (<50) using small plasmonic noble metal nanoparticles at solid-liquid interfaces. Here, we show that employment of almost continuous noble metal layers results in significantly stronger...
متن کاملSurface-Enhanced Infrared Absorption
Molecules adsorbed on metal island films or particles exhibit 10–1000 times more intense infrared absorption than would be expected from conventional measurements without the metal. This effect is referred to as surface-enhanced infrared absorption (SEIRA) to emphasize the similarities with surface-enhanced Raman scattering (SERS). The electromagnetic interactions of the incident photon field w...
متن کاملAll-Semiconductor Plasmonic Resonator for Surface-Enhanced Infrared Absorption Spectroscopy
Infrared absorption spectroscopy remains a challenge due to the weak light-matter interaction between micron-wavelengthed infrared light and nano-sized molecules. A highly doped semiconductor supports intrinsic plasmon modes at infrared frequencies, and is compatible with the current epitaxial growth processing, which makes it promising for various applications. Here, we propose an all-semicond...
متن کاملDouble-layered nanoparticle stacks for surface enhanced infrared absorption spectroscopy.
We demonstrate that double-layered stacks of gold and insulator nanoparticles arranged on a flat gold surface dramatically enhance the sensitivity in absorption infrared microscopy. Through morphological variations of the nanoparticles, the frequency of the plasmon resonances can be tuned to match the frequency of the molecular vibration in the mid-infrared region. The results show that the nan...
