Summary on Grant Application Form |
|
An optical scanning probe microscope (SPM) will be constructed in which the probe tip to sample distance, z, will be controllable over a large range from the nanoscopic near-field regime (z< 100 nm) to the far-field (z> lambda); importantly it includes the much ignored meso-optical regime between these limits which is crucial to understanding tip-sample interaction. To what extent does a tip, especially a metallised tip, perturb the optical response of the sample it is probing? How does an image evolve in going from the far to the near-field? Can the absolute value of z be determined? In addition to addressing such basic questions the project tackles the dynamics of surface plasmon excitations, near-field magneto-optical imaging and spectroscopic applications, in particular intriguing techniques in which surface plasmons are launched at cells occupying nano-holes in a metal film. A broad range of diagnostic applications is envisaged by our collaborators at CAMR who have pioneered the technique. The magneto-optical imaging is, of course, pertinent to ultra-high density data storage. In addressing a range of problems of basic scientific concern and forward looking industrial interest, the project has clear potential in terms of `improving economic competitiveness'.
