Accelerated Development of a High Field Single Electron Spin Microscope

Abstract : This program has significantly accelerated the construction of a Single Electron Spin Microscope (SESM) - by this time practically completed - and the ideas proposed has been successfully realized. In this final report we emphasize those aspects of the SESM construction where funding provided under this pilot project made a substantial difference in the planning and design phase of the development even if additional funds were required for the eventual realization such as: (1) Development and design of stiff cantilever allowing for stable SPM operation and control at sub nanometer sample - tip separations. (2) Broadband detection of the cantilever motion is fed into a computer cluster for real time analyzes; complex distributed software has been developed for that. (3) Satisfactory millimeter wave excitations have been achieved with the developed mm wave power amplifiers and strip-line resonators. At the time of writing this report the SESM construction is practically accomplished. While performance refinements and enhancements are continuously added as a result of our ongoing efforts to find optimum-working configuration our current focus is to learn to use the instrument to explore the potentials built into it.
