The development of scanning tunneling microscopy (STM), like that of many instruments in physics, opens new windows to the physical world. The ability to resolve surface topographies on an atomic scale, and to produce energy spectra down to the μeV regime allows us to explore properties of exciting yet poorly-understood new materials. In this talk I will provide a brief introduction to high-temperature superconductors as an example of an exotic material and how STM can help answer some unsolved questions. I will discuss the design, construction, and characterization of LC-π metal powder filters I developed as part of my Master thesis, and how these filters play a crucial role in improving energy resolution. These topics are presented at a relatively basic level, with the intention of providing an introductory understanding for all graduate students.
