Measuring the reactivity of a silicon-terminated probe (2016)
Journal Article
Sweetman, A., Stirling, J., Jarvis, S. P., Rahe, P., & Moriarty, P. (2016). Measuring the reactivity of a silicon-terminated probe. Physical Review B, 94(11), Article 115440. https://doi.org/10.1103/PhysRevB.94.115440

It is generally accepted that the exposed surfaces of silicon crystals are highly reactive due to the dangling bonds which protrude into the vacuum. However, surface reconstruction can not only modify the reactivity of bulk silicon crystals, but play... Read More about Measuring the reactivity of a silicon-terminated probe.

A combined Monte Carlo and Hückel theory simulation of orientational ordering in C60 assemblies (2016)
Journal Article
Leaf, J., Stannard, A., Jarvis, S. P., Moriarty, P., & Dunn, J. L. (2016). A combined Monte Carlo and Hückel theory simulation of orientational ordering in C60 assemblies. Journal of Physical Chemistry C, 120(15), https://doi.org/10.1021/acs.jpcc.6b00638

Orientational ordering of C60 molecules within monolayer and multilayer islands is a regularly observed phenomenon in scanning tunnelling microscopy (STM) studies. Here we simulate the orientational ordering seen in STM images via a novel combination...

Visualizing the orientational dependence of an intermolecular potential (2016)
Journal Article
Jarvis, S. P., Rashid, M. A., Sweetman, A., Rashid, M. A., Jarvis, S. P., Dunn, J. L., Rahe, P., & Moriarty, P. (2016). Visualizing the orientational dependence of an intermolecular potential. Nature Communications, 7, Article 10621. https://doi.org/10.1038/ncomms10621

Scanning probe microscopy can now be used to map the properties of single molecules with intramolecular precision by functionalization of the apex of the scanning probe tip with a single atom or molecule. Here we report on the mapping of the three-di... Read More about Visualizing the orientational dependence of an intermolecular potential.

Intermolecular artifacts in probe microscope images of C60 assemblies (2015)
Journal Article
Jarvis, S. P., Rashid, M. A., Sweetman, A., Leaf, J., Taylor, S., Moriarty, P., & Dunn, J. (2015). Intermolecular artifacts in probe microscope images of C60 assemblies. Physical review B: Condensed matter and materials physics, 92(24), https://doi.org/10.1103/PhysRevB.92.241405

Claims that dynamic force microscopy has the capability to resolve intermolecular bonds in real space continue to be vigorously debated. To date, studies have been restricted to planar molecular assemblies with small separations between neighboring m...

Physisorption controls the conformation and density of states of an adsorbed porphyrin (2015)
Journal Article
Jarvis, S. P., Taylor, S., Baran, J. D., Thompson, D., Saywell, A., Mangham, B., Champness, N. R., Larsson, J. A., & Moriarty, P. (2015). Physisorption controls the conformation and density of states of an adsorbed porphyrin. Journal of Physical Chemistry C, 119(50), 27982-27994. https://doi.org/10.1021/acs.jpcc.5b08350

Conformational changes caused by adsorption can dramatically affect a molecule’s properties. Despite extensive study, however, the exact mechanisms underpinning conformational switching are often unclear. Here we show that the conformation of a proto...

Measuring the mechanical properties of molecular conformers (2015)
Journal Article
Jarvis, S. P., Taylor, S., Baran, J., Champness, N. R., Larsson, J., & Moriarty, P. (2015). Measuring the mechanical properties of molecular conformers. Nature Communications, 6(8338), https://doi.org/10.1038/ncomms9338

Scanning probe-actuated single molecule manipulation has proven to be an exceptionally powerful tool for the systematic atomic-scale interrogation of molecular adsorbates. To date, however, the extent to which molecular conformation affects the force... Read More about Measuring the mechanical properties of molecular conformers.

Nano-contact microscopy of supracrystals (2015)
