Feasibility of Single-Point Excitation Ultrasonic Force Microscopy
… the measurable range for either the Atomic Force Microscope (AFM) or the Scanning Tunnelling Microscope (STM). We use the Rayleigh surface wave as our simple physical model. By applying the model to two commercial probes and four common samples, we have shown that the predicted amplitude of …

Atom-by-Atom Substitution of Transition Metals in GaAs and Visualization of Hole-Mediated Interactions
… atom-by-atom substitution technique with the scanning tunnelling microscope (STM) to controllably incorporate transition metal dopants into GaAs. We compare the electronic states of isolated single acceptors in an identical configuration - Ga sites in the top layer of a GaAs surface. The …

Scanning Probe Study of N-Heterocyclic Carbene Self-Assembly on Coinage Metal Surfaces
… Using a low-temperature ultra-high vacuum scanning tunnelling microscope (STM), this work provides a molecular-level study of NHC self-assembly on several surfaces. The work contained in this thesis begins with a study of NHC-IiPr on Au(111), the imidazole analogue of NHC-iPr. It was found …

MoS2 on Gold: achieving extremely high exfoliation yield and optical contrast for Van der Waals monolayers
… excited plasmonic tunnel junctions with a scanning tunnelling microscope (STM) was carried out to work towards integrating 2D materials as tunnelling barriers in various tunnel junction architectures.<br/><br/>Extremely large coverage of exfoliated monolayer MoS2 was observed on freshly …
