Temperature Dependence of Phonon Energies and Lifetimes in Single- and Few-layered Graphene
Markos Poulos, Konstantinos Papagelis, Emmenuel N. Koukaras +3
In this work, we have studied the phonon properties of multi-layered graphene with the use of Molecular Dynamics (MD) simulations and the k-space Autocorrelation Sequence (k-VACS)…
Tunable macroscale structural superlubricity in two-layer graphene via strain engineering
Charalampos Androulidakis, Emmanuel N. Koukaras, George Paterakis +2
Achieving structural superlubricity in graphitic samples of macro-scale size is particularly challenging due to difficulties in sliding large contact areas of commensurate stacking…
Compression behavior of simply-supported and fully embedded monolayer graphene: theory and experiment
Emmanuel N. Koukaras, Charalampos Androulidakis, George Anagnostopoulos +2
Single layer graphene simply-supported on a polymer substrate was subjected to axial compression and its behavior upon loading was monitored with laser Raman spectroscopy (LRS). Th…
Wrinkled few-layer graphene as highly efficient load bearer
Charalampos Androulidakis, Emmanuel N. Koukaras, Jaroslava Rahova +5
Multilayered graphitic materials are not suitable as load-bearers due to their inherent weak interlayer bonding (for example, graphite is a solid lubricant in certain applications)…
Suspended Monolayer Graphene under True Uniaxial Deformation
Ioannis Polyzos, Massimiliano Bianchi, Laura Rizzi +5
2D crystals, such as graphene, exhibit the higher strength and stiffness of any other known man-made or natural material. So far, this assertion has been primarily based on modelli…
Stress Transfer Mechanisms at the Submicron Level for Graphene/Polymer Systems
George Anagnostopoulos, Charalampos Androulidakis, Emmanuel N. Koukaras +5
The stress transfer mechanism from a polymer substrate to a nano-inclusion, such as a graphene flake, is of extreme interest for the production of effective nanocomposites. Previou…
