In second year at ESPCI, students come to my laboratory to make practical courses, most of them being more or less related to quantum mechanics : radioactivity, ESR, RMN, optical pumping ... and STM. I am more specifically in charge of the STM experiment this year. A Nanosurf aparatus is used to study the surface of graphite : imaging with atomic resolution, I-V characteristics and spectroscopy, exponential decay of the tunneling current as a function the distance. Then a fresh gold layer is evaporated by the students, and imaged by STM.
