Abstract
The scanning tunneling microscope (STM) scans the surface of a given material and maps out the topography of the surface at the atomic level. This tool is useful for analyzing the atomic structure of the given material and for further research in material science. By using a stylus to tunnel a narrow beam of electrons. This relationship is very sensitive and as the stylus glides over the surface of the material, the stylus head will move up and down to maintain that precise distance. The machine then detects these movements and maps out what it reads on a three dimensional graph.
Biography
Sarah Skinner is a freshman at Missouri S&T. She is pursuing a bachelor’s in physics. She was recently taken under the wing of the FYRE (First Year Research Experience) program and given this wonderful opportunity of correcting the STM’s malfunction. She is also a Second Degree Black Belt of the Midwest Taekwondo Association.
