Dataset for "Common source of light emission and nonlocal molecular manipulation on the Si(111)-7x7 surface"
This dataset contains data supporting the results presented in the paper "Common source of light emission and nonlocal molecular manipulation on the Si(111)-7x7 surface". It includes the data used to plot each figure associated with this publication, together with the raw oscilloscope data in .csv format.
The study combines the results of the two near identical experimental techniques - nonlocal atomic manipulation and light emission from a scanning tunnelling microscope - for the system of toluene molecules chemisorbed on the Si(111)-7×7 surface at room temperature. The radial dependence of molecular desorption away from the tip injection site conforms to a two-step ballistic-diffusive transport of the injected hot electrons across the surface, with a threshold bias voltage of +2.0 V. We find the same threshold voltage of +2.0 V for light emission from the bare Si(111)-7×7 surface. Comparing these results with previous published spectra we propose that both the manipulation and the light emission follow the same hot electron dynamics, only differing in the outcome of the final relaxation step which may result in either molecular manipulation, or photon emission.
