  Abstract: The difficulty of obtaining clean surfaces makes conducting experimental surface science research with undergraduate students challenging. Research has shown that it is possible to grow thin metal films epitaxially on ordered Si substrates in low vacuum, resulting in clean, ordered surfaces available for study. The results of several student capstone research projects dealing with the growth by thermal evaporation of Cu thin films on etched Si(100) substrates will be presented. Resistivity was measured during growth and analyzed using a Fuchs-Sondheimer scattering model. Theta-2 theta X-ray diffraction was used to examine epitaxy normal to the surface after growth. The critical step in the preparation of the Si(100) is etching in hydrofluoric acid (HF). The etching time and HF concentration were varied to study possible effects on the copper’s epitaxy.
