The ultrasonic/shear-force microscope: Integrating ultrasonic sensing into a near-field scanning optical microscope

An ultrasonic transducer is incorporated into a near-field scanning optical microscope NSOM to augment its versatility to characterize the properties of layers adsorbed to a sample’s surface. Working under typical NSOM operation conditions, the ultrasonic transducer—attached underneath the sample—demonstrates sufficient sensitivity to monitor the waves generated by the tapered NSOM probe that o...

Scanning Microwave Microscope

Introduction Measuring electromagnetic properties of materials can provide insight into applications in many areas of science and technology, and increasingly, these properties need to be evaluated at the nanometer scale. Since electromagnetic properties, such as the dielectric constant, are ultimately related to a material’s molecular structure, correlating the detailed physical structure of a...

The near-field scanning thermal microscope.

We report on the design, characterization, and performance of a near-field scanning thermal microscope capable to detect thermal heat currents mediated by evanescent thermal electromagnetic fields close to the surface of a sample. The instrument operates in ultrahigh vacuum and retains its scanning tunneling microscope functionality, so that its miniature, micropipette-based thermocouple sensor...

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...
