Development of an Analytical Photon Scanning Tunneling Microscope
Abstract
In this program sponsored by the ARO Physics office we have made significant progress in designing, constructing and using a novel device called the Near-field Scanning Optical Microscope, or NSOM. The microscope is one of a family of instruments which use either small apertures or finely sharpened probes to scan the surface of a sample and thereby construct an image of that surface. Since demonstrating the utility of the microscope of our design, we have subsequently built a number of other NSOMs incorporating a variety of illumination modes and signal transduction methods in imaging surfaces and taking optical spectra of features on these surfaces. Theoretical efforts to model the optical throughput of the probe have been undertaken, and the initial results have been published. The program has supported several students, including a student who, after graduation, designed the first commercial NSOM instrument.
