Nanofabricated tips for device-based and double-tip scanning tunneling microscopy

Large-scale atom manipulation on an ionic surface and its prospects

In this thesis, a technique is developed to manipulate individual atoms on an ionic surface, with great precision and at a large scale, to study the quantum mechanical properties of atomic assemblies on the nanoscale.<br/><br/>We use the needle of a scanning tunnelling microscope (STM) to approach missing atoms - vacancies - in a chlorine...

Fast and reliable pre-approach for scanning probe microscopes based on tip-sample capacitance

Within the last three decades Scanning Probe Microscopy has been developed to a powerful tool for measuring surfaces and their properties on an atomic scale such that users can be found nowadays not only in academia but also in industry. This development is still pushed further by researchers, who continuously exploit new possibilities of...
