Operation of Cold STM System In Conjunction With In Situ Molecular Beam Epitaxy

Procedures for operating an STM designed to operate with the surfaces being imaged at temperatures between 4.2-323 K were adjusted to be applied to the system, the system's performance was tested, and aspects of the system were modified. The procedures include the outline of methods for cooling the system, an outline of many of the parameters for annealing tips, and a method for leak detection. Aspects of the system tested for performance were tip annealing, isolation of the system from noise, vacuum quality, system cooling, sample growth and STM scanning. The modifications included a new filament for annealing, an additional noise dampener made of rubber, and removal of vacuum leaks.
