A dilution refrigerator based scanning tunneling microscope for high resolution nanoscale spectroscopy Delaney, Robert
Abstract
This thesis describes the design, construction and fabrication of a complete ultra-high vacuum (UHV) Dilution refrigerator based scanning tunneling microscope (STM). Data taken at a base temperature of 114 mK is presented and electrical, mechanical and vacuum design features are described for both the STM and the UHV system. Topographic images and spectroscopy on Au(111), graphene and other materials are presented to detail the performance of the STM. Techniques involving coherence and finite element analysis are used to address acousto-mechanical interaction between the STM and an acoustic room mode. The design and fabrication of an electron beam heater sample plate and complete UHV sputtering and annealing stage are presented.
