Scanning tunneling microscopy (STM) has been proven to be an extremely powerful tool for studying the electronic structures of solid-state systems. The STM topographic images, assisted by other surface analysis techniques with chemical specifity, lead to the structural determination of clean and adsorbate-covered surfaces. For example, the first atomically resolved STM image in history confirme...

The recently developed technique Scanning Tunneling Microscopy in the Field Emission regime (STM FE) is based on the Russell Young's topografiner technology [1]. The set-up is a no contacting device consisting of a sharp tip approached vertically to a conducting surface at variable distances and biased with a small voltage with respect to the surface (Figure 1). The system builds a junction acr...

We give an introduction to spin-polarized scanning tunneling microscopy (SpSTM), a magnetic imaging technique with nanometer lateral resolution. Sp-STM allows to record constant current images which represent the electron density near the sample surface and simultaneously the spin polarization of the electron density which is related to the magnetic moment. It is shown how magnetic and topograp...

We present here the historic development of Scanning Tunneling Microscopy; the physical and technical aspects have already been covered in a few recent reviews and two conference proceedings [l] and many others are expected to follow in the near future. A technical summary is given by the sequence of figures which stands alone. Our narrative is by no means a recommendation of how research shoul...

In order to achieve a better understanding of how scanning tunneling microscopy (STM) images of metallo-complexes are related to the geometric and electronic structure, we performed scanning microscopy (STM) and scanning tunneling spectroscopy (STS) techniques on [FeFe3L6] (L= N-methylaminediethanolate) star-type tetranuclear molecular magnet. The experiments were performed under ambient condit...
