Abstract
Scanning tunneling microscopy (STM) is a technique that is used to take atomic-scale images. Using the STM, the surface of a curved silver crystal was imaged after it had been exposed to atomic oxygen (AO). The images were then analyzed, looking at the differences of the features on a silver’s surface. My project specifically looked at absorption patterns. A homogeneous pattern shows oxygen migrates from the surface to subsurface of the crystal at random locations; there would be no pattern predicting where it absorbs. A heterogeneous process shows migration around defects where oxygen would dominate areas.
