Atom Manipulation with the LT STM. 42 Ag atoms arranged to an Omicron Logo on a Ag(111) surface at 4.8 K. The parameters were Ugap= -20 mV, IT= 10 nA for imaging and Ugap= -10 mV, IT= 300 nA for atom manipulation, respectively. The probability for atom manipulation was nearly 1 when using these parameters. Measurements by A. Bettac, Omicron NanoTechnology, Germany. |
