Beschreibung:
  • The W(110)/C-R(15x3) reconstructed surface has been studied by STM at variable tip-surface separation controlled by the tunneling gap resistance. A pronounced dependence of the STM image contrast as a function of tip height has been observed which is explained by the suppression of higher Fourier components, i.e. small wavelength features, with increasing tip height and an additional spatial dependence of the decay length of the surface wave-function. As an important implication of our study we have found that STM images of non-trivial surface structures can depend critically on the tunneling gap resistance. © Springer-Verlag 1996.
