Abstract
Light incident on a total internal reflection surface will tunnel thro ugh a submicrometre gap in the presence of a dielectric surface. This tunnelling phenomenon is used in the photon tunnelling microscope to i mage polyethylene single crystals, providing a topographical map of th e single-crystal surface. Tunnelling increases exponentially with samp le height and is quantified using video photometry of the grey-scale t unnelling image.
