Abstract
First application of the new Lithium Surface Diffusion Metal ion source in the Scanning Tunneling Microscope (STM) mode under UHV conditions is reported. By applying 5-10 μs voltage pulses to the Li-covered W tip placed within tunneling range, single Li hillocks (40×40 nm) as well as Li nanostructures are deposited on the chosen area of the Pt(110) sample in a well-reproducible way. The topography and evolution of the created Li-nanoformations can be immediately probed using the same tip in the STM imaging mode
