In this research MoS2 on gold samples have been fabricated. Several different fabrication procedures have been tested including stamping, gold-mediated exfoliation and hydrogen plasma cleaning. Measurements identifying the 2H phase have been made using Atomic Force Microscopy and Low Energy Electron Microscopy. Although 1T’ could not be observed, insights are gained into the various fabrication processes.Show less

The first part consist mainly of theory and there are no measurement results to support the theory, the second part describes a Matlab simulation of a random walk of a ATTO 647N molecule close to a gold nanorod that is being placed in an electromagnetic field. The simulation uses the MNPBEM toolbox to calculate the electric field generated by the gold nanorod and a random walk for the movement of the molecule.Show less
