  • Nanoscale stoichiometric modifications and surface charge patterning of La[sub]{1.975}Sr[sub]{0.025}CuO[sub]{4+[delta]} crystals with a biased atomic force microscope tip [Elektronski vir]
    Strojnik, Martin ...
    The application of a positive or negative local bias to the surface of La[sub]{1.975}Sr[sub]{0.025}CuO[sub]{4+[delta]} (LSCO) crystal by a conducting atomic force microscope tip results in ... accumulation of a (positive or negative respectively) metastable charge on the surface. The surface charge initially shows diffusive dynamics with a timescale of hours, but thereafter it is shown to be stable for months. The charged regions are found by Auger electron spectroscopy to have a different stoichiometry from the surrounding material. A part from fundamental implications for the heterostructure device construction, such surface charge manipulation could lead to AFM nanopatterning of superconducting nanoscale device and applications memories.
