Summary on Grant Application Form |
|
In the last two years, we have developed a non-contact, shear-force controlled SNOM. The technique measures the amplitude and phase of the driven probe using an interferometer and lock-in amplifier. We will exploit the exceptional sensitivity of this AFM and of the SNOM capability in several ways both as a microscope and as a tool in nanolithography. We will focus on polymer systems. By measuring the local optical properties, in particular birefringence and absorption, we will determine local orientation and phase structure on the tens of nanometre scale. The SNOM illuminates a small volume in a thin film of photoresist and so can be used to create structures on the 20 nm scale using this instrument. The feasibility of creating smaller light sources than the possibilities offered using the existing aperture methods will be investigated for higher resolution optical imaging. for the interpretation and for the development of SNOM, theoretical calculations of SNOM imaging will be developed in concert with experiment.
