It is presented a topographical study on the formation of thin films of gold on muscovite mica. The characterization of the samples was done through STM and AFM. A set of samples of the same thickness, evaporated at different substrate temperature (between -160 and 260 °C) and another set of samples evaporated, at room temperature varying thickness (between 1.5 and 33 nm) was performed. The results show that gold has a three-dimensional growth through the formation of grains; these are isolated or forming nanowires to 6 nm thick, which completely cover the substrate above 8 nm thick. The average grain diameter is constant up to 8 nm thick and increase with the thickness for higher deposition. The average grain diameter is similar for films of the same thickness regardless of the temperature of the substrate.

    In tunneling microscopy a potential barrier separates a pointed tip from the sample to be investigated. In this letter we show that atomic resolution can be achieved in special cases where the gap spacing has been reduced to the point where the potential barrier may have completely collapsed. In...
