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)…
Optical detection of strain and doping inhomogenieties in single layer MoS2
Antonios Michail, Nick Delikoukos, John Parthenios +2
Van der Waals single-layer materials are characterized by an inherent extremely low bending rigidity and therefore are prone to nanoscale structural modifications due to substrate…
Evaluating arbitrary strain configurations and doping in graphene with Raman spectroscopy
Niclas S. Mueller, Sebastian Heeg, Miriam Peña Alvarez +13
Raman spectroscopy is a powerful tool for characterizing the local properties of graphene. Here, we introduce a method for evaluating unknown strain configurations and simultaneous…
Compression Behavior of Single-layer Graphene
Otakar Frank, Georgia Tsoukleri, John Parthenios +5
Central to most applications involving monolayer graphene is its mechanical response under various stress states. To date most of the work reported is of theoretical nature and ref…
Subjecting a graphene monolayer to tension and compression
Georgia Tsoukleri, John Parthenios, Konstantinos Papagelis +5
The mechanical behaviour of graphene flakes under both tension and compression is examined using a cantilever-beam arrangement. Two different sets of samples were employed involvin…
Biaxial Tensile Strain Enhances Electron Mobility of Monolayer Transition Metal Dichalcogenides
Jerry A. Yang, Robert K. A. Bennett, Lauren Hoang +7
Strain engineering can modulate the material properties of two-dimensional (2D) semiconductors for electronic and optoelectronic applications. Recent theory and experiments have fo…
