Auger electron survey of a Cu(111) surface after repeated rounds of Ar+ sputtering and annealing in the preparation chamber of the STM end station. The spectrum is dominated by Cu features, with both S and C detectable. The measurement is made with an RBD microCMA. Credit: Seth Shields
Scanning Tunneling Spectroscopy (STS) spectra of a Cu(111) surface at cryogenic temperatures. The current set point and the number of averages are varied, affecting the timing and the signal to noise achieved. The Shockley surface state of Cu(111) is visible under all settings. Credit: Seth Shields
Scanning Tunneling Microscopy (STM) scans of a Cu(111) surface in a topographic mode and in a dI/dV mode. CO molecules adsorbed to the surface are present with an expected ring pattern surrounding each. Credit: Seth Shields
