1. Design and Construction of Low-Temperature Scanning Tunnelling Microscope for Spectroscopy
Abstract : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. READ MORE

3. Scanning probe techniques as an investigation tool for semiconductor nanostructures and devices
Abstract : Semiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage. This includes harvesting of energy (solar cells) and saving of energy, e.g. in lighting (light-emitting diodes, LEDs) and transfer of energy (power devices). READ MORE

4. Electronic states of adsorbates and insulating overlayers on metal surfaces
Abstract : Electronic states of adsorbates and insulating overlayers provide a wealth of scientifically interesting phenomena with great technological importance. Interesting phenomena arise, for example, from the interaction of electronic states of an adsorbate with the continuum of metal electron states, both propagating bulk states and surface states.

5. Scanning Probe Microscopy: Design and Applications
Abstract : A compact scanning tunneling microscope (STM) and a scanning ion-conductance microscope (SICM) has been constructed. The concentric microscope head was built around a commercial piezoelectric inchworm motor that was used for coarse positioning. The microscope has a high resonance frequency (9.6 kHz), low noise (0.
