N2 - We report on high resolution imaging by a collection-mode photon scanning tunneling microscope (c-mode PSTM). In our PSTM system, we have used a novel probe with a nanometric protrusion formed from a metal coated sharpened fiber. By using this probe, flagellar filaments of salmonella of diameter 25 nm could be imaged to have a full width at half maximum of 50 nm. Obtained images strongly depended on the separation of the sample to the probe, the diameter of the aperture, and polarization of the irradiated light. Comments on the origins of these dependencies are given.
