Tunable Fermi resonance in a C2F6 monolayer on graphite

The infrared absorption spectrum of C2F6 physisorbed on graphite in the commensurate 232 phase has two strong, narrow peaks associated with the n5 molecular vibration. They are interpreted as a Fermi resonance between n5 and the n81n11 combination band, which are shifted into near-coincidence by dynamic dipole coupling between the adsorbate molecules. The splitting and relative strengths have b...

Charge localization around disclinations in monolayer graphite

Using a continuum model, we obtain qualitative results that imply charge localization around negative curvature disclinations (i.e. rings with more than 6 Carbon atoms) in a graphite sheet. Conversely, it is found that positive curvature disclinations repel charge, independent of its sign.

Tetrafluoromethane monolayer physisorbed on graphite : its orientational walls and its complex phase diagram

2014 Neutron diffraction results for a monolayer of CF4 physisorbed on different graphites show the complexity of the system, mainly due to the non spherical shape of the admolecule. From our neutron data and LEED results [6] we recognize at least 6 different phases. These are, with decreasing temperature, liquid, plastic, commensurate solid, incommensurate solid, incommensurate tilted and a su...
