3. Fabrication and Characterization of Aluminum Single Electron Transistors for Scanning Probes
Sammanfattning : The main objective of the work presented in this thesis was to fabricatescanning single electron transistor probes that operate at pumped liquid heliumtemperatures. This required single electron transistors (SETs) with low resistance (R_) and relatively high charging energy (E_C), and the technology tointegrate SETs onto probes. LÄS MER

5. Theoretical modeling of scanning tunneling microscopy
Sammanfattning : The main body of this thesis describes how to calculate scanning tunneling microscopy (STM) images from first-principles methods. The theory is based on localized orbital density functional theory (DFT), whose limitations for large-vacuum STM models are resolved by propagating localized-basis wave functions close to the surface into the vacuum region in real space.
