M.Ing. / This dissertation provides a review of the most notable papers published with regard to the specific performance characteristics of Tunnel Boring Machines (TBM's) during the past twenty years. It is a literature study of a Bibliography of 57 publications, which were screened from an original list of 970 documents ...

The ultimate intent of this research program is to produce nanosized magnetic tunneling junctions, and to study the physical properties of such devices. The physical phenomena of nanosized tunneling junctions are significantly different than that of currently popular micro-sized junctions. There is a considerable amount of work that must be done prior to producing these new junctions to ensure that good measurements can be carried out once the structures have been built. This thesis describes the efforts taken to design a measurement platform that will accurately measure tunneling magnetoresistance (TMR) in nanosized Magneto-tunneling Junctions (MTJ). The testing done with this system at various stages throughout the design and testing process confirm the expectations for the performance of the system. Voltage-current measurements can be performed on objects ranging from a few nanometers in size to micrometer sized. Traditional micro-sized MTJs have not been excluded in this design.

In the scope of this master thesis, a home-made brass scanning tunneling microscope (STM) was machined, assembled and tested for its functionality. For this microscope, a new approach-technique was used which follows the design suggested by Pan. The difference to Pan's design is the use of piezoplates, instead of piezostacks. Hence, the approach is still based on the stick and slip motion, but it allows the microscope to be more compact. A new and simple electronic circuit, in order to control the approach, is presented and was put together. This circuit is based on mechanical relays, which provide a sufficient long time gap between the single moving steps, due to their mechanical functional principle. Subsequently the approach-technique and the scanning was successfully tested. Finally, first images of HOPG were taken under ambient conditions. / text
