Study of Semiconductor Clusters by Local Inverse Photo Emission
Abstract
We have completed the project of building the first system consisting of a scanning tunneling microscope operating in ultra-high vacuum, and all the components are now operational. STM images of charge-density waves in UHV have been successfully obtained. We have developed and operated two other systems that enable us to perform the task delineated in the original ONR proposal. The second system is a computerized nanolithography station where computer generated patterns drive the STM tip, which deposits atoms at the pre-prescribed locations. The third system measures the photon emission from nanostructures using a cooled photomultiplier, a photon counter, and an image processor. We are currently writing several papers that describe the theory of photon emission from STM-deposited patterns and the various experiments performed with these three systems. Enclosed is a list of publications describing our STM work. Future plans call for the refinement of the experiments where clusters are written and their light emission recorded and analyzed topographically and spectroscopically.
