2003 journal article

The effects of probe boundary conditions and propagation on nano-Raman spectroscopy

JOURNAL OF MICROSCOPY-OXFORD, 210(3), 252–254.

By: H. Hallen n , E. Ayars* & C. Jahncke*

Event: at UK

author keywords: boundary conditions near a metal; electric field enhancement; gradient-field Raman; KTP; light propagation in the near-field; nano-Raman; near-field Raman spectroscopy; near-field scanning optical microscopy; resolution
TL;DR: Raman spectra obtained in the near‐field, with collection of the Raman‐shifted light in reflection, show selective enhancement of vibrational modes, and the enhancement of certain Raman forbidden vibrations is explained by the presence of an electric field gradient near the metal‐apertured fibre probe.

2001 article

Fundamental differences between micro- and nano-Raman spectroscopy

Ayars, E. J., Jahncke, C. L., Paesler, M. A., & Hallen, H. D. (2001, April). JOURNAL OF MICROSCOPY-OXFORD, Vol. 202, pp. 142–147.

By: E. Ayars n, C. Jahncke*, M. Paesler n & H. Hallen n 

Event: at UK

author keywords: infrared spectroscopy; near-field optical microscopy; Raman spectroscopy
TL;DR: For nano‐Raman spectroscopy with an NSOM, selection rules allow for the detection of active modes with intensity dependent on the field gradient, which can have similar activity as infra‐red absorption modes. (via Semantic Scholar)

2000 journal article

Electric field gradient effects in Raman spectroscopy

PHYSICAL REVIEW LETTERS, 85(19), 4180–4183.

By: E. Ayars n, H. Hallen n  & C. Jahncke*

TL;DR: A theoretical model is developed for this "gradient-field Raman" effect, which can explain the origin and intensity of some Raman modes observed in SERS and through a near-field optical microscope (NSOM-Raman). (via Semantic Scholar)

1999 journal article

Proximal electromagnetic shear forces

Journal of Microscopy, 196(1), 59–60.

By: E. Ayars n, D. Aspnes n , P. Moyer* & M. Paesler n

TL;DR: A simple model calculation is performed to estimate the electromagnetically induced shear force caused by a current dissipation when a charged tip is moved parallel to a conducting material. (via Semantic Scholar)
