Development of Scanning Near-field Optical Microscope Using a Spherical Small Protrusion as a Probe.

Near-field scanning optical microscope probe analysis.

In this article results of a comparison of two NSOM probe characterization methods are presented. Scanning electron microscopy analysis combined with electromagnetic field modeling using the finite difference in time domain method are compared with measured far-field radiation diagrams of NSOM probes. It is shown that measurement of far-field radiation diagrams can be an efficient tool for dail...

Near-field optical microscope using a silicon-nitride probe

Operation of an alternative near-field optical microscope is presented. The microscope uses a microfabricated silicon-nitride probe with integrated cantilever, as originally developed for force microscopy. The cantilever allows routine close contact near-field imaging on arbitrary surfaces without tip destruction. The effect of adhesion forces on the coupling to the evanescent wave has been obs...

Observation of nanostructure by scanning near- field optical microscope with small sphere probe

Step and terrace structure has been observed in an area of 1 mm 1 mm on the cleaved surface of KCl–KBr solid-solution single crystal by scanning near-field optical microscope (SNOM) with a small sphere probe of 500 nm diameter. Lateral spatial resolution of the SNOM system was estimated to be 20 nm from the observation of step width and the scanning-step interval. Vertical spatial resolution wa...

Studying of various nanolithography methods by using Scanning Probe Microscope

The Scanning Probe Microscopes (SPMs) based lithographic techniques have been demonstrated as an extremely capable patterning tool. Manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. In this paper, a qualified overview of diverse lithog...
