Enhanced image contrast with delocalized near‐field excitation. Issue 9 (6th January 2014) - Sánchez, E.
Abstract Making highly resonant tip geometries via nanofabrication can be a difficult process, while the aperture/detector method is a much easier to implement. With this technique, even tips with undesirably low resonance can be utilized for imaging. We demonstrate the concept through the use of a low field enhancement probe by showing the spatial separation of the excitation and field enhancement locations and the associated numerical modeling.
