AFM can be employed in ambient and liquid environments as well as in vacuum and at low and ultralow temperatures. The technique is an offspring of scanning tunneling microscopy (STM), where the tunneling tip of the STM is replaced by using a force sensor with an attached tip.

Although these tweezers are made from non-magnetic stainless steel, magnetization can occur in the presence of strong magnetic fields. Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for the analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM) and it supports a lot of SPM data formats . However, it can be used for general height field and (greyscale) image It is a high quality allrounder SPM delivering broad scientific output and regularly groundbreaking results employing usually more than one technique. Its base is an ultra-stable platform offering a large range of operation modes including STM, QPlus AFM, STS, IETS, force spectroscopy, optical experiments and atom manipulation.

This is done by moving the tip of the manometer across the surface of the image.

STM/AFM - overview. Some twenty years ago at IBM's Almaden Research Center in San Jose, in a small lab packed with high-tech equipment in the hills of Silicon Valley, IBM researchers achieved a landmark in mankind's ability to build small structures.

We present a numerical STM/AFM model, which takes into account the relaxation of the probe due to the tip-sample interaction. Scanning tunneling microscopy (STM) is different to AFM, in that it uses tunneling electrons and the piezoelectric effect to generate an image of a surface.

One set of experiments suitable for TEM-STM concerns an unknown STM tip as well as an interacting sample, which is a limiting factor in the interpretations of STM data. The same is true for the atomic force microscope (AFM). In the AFM the force is measured by the deflection of a cantilever that supports the tip. The cantilever deflection, however, may
