The research lines performed within the SPM area are framed in the fields of Physics, Chemistry and Biology, with strong focus in Nanoscience. Supported by the strong background in magnetism both at INA/UZ and ICMA in Zaragoza, an important goal is to explore its limits at the atomic scale. In this sense, the low temperature UHV facilities provides the possibility of growing magnetic nanostructures (nanowires, atomic chains, quantum corrals) and resolve magnetic information at the atomic scale.
In addition, the new tools will also allow the establishment of new initiatives, indeed new in Zaragoza. In relation with biology, the focus is centered on using force spectroscopy to resolve intermolecular forces that govern recognition between biomolecules. This approach can be also extended down to the atomic scale with a newly developed method, the qPlus sensor STM, which allows to measure and quantify weak interaction forces between single molecular groups. Furthermore, a constitutive interest is being developed in exploring the fundamental properties of electronic transport through individual molecules and through molecular selfassemblies.
The goal is to identify molecular-active channels, and the related charge quantization effects, that may be extended to molecular-based electronic devices. In this sense, the use of an electrolyte as an external gating is more than an attractive endeavor.More specifically, the research lines are structured as follows:
The main research lines in Scanning Probe Microscopy are:
