Structural dynamics of polycrystalline graphene
Zihua Liu, Debabrata Panja, Gerard T. Barkema
The exceptional properties of the two-dimensional material graphene make it attractive for multiple functional applications, whose large-area samples are typically polycrystalline.…
Efficient structural relaxation of polycrystalline graphene models
Federico D'Ambrosio, Joris Barkema, Gerard T Barkema
Large samples of experimentally produced graphene are polycrystalline. For the study of this material, it helps to have realistic computer samples that are also polycrystalline. A…
Discontinuous evolution of the structure of stretching polycrystalline graphene
Federico D'Ambrosio, Vladimir Juričić, Gerard T. Barkema
Polycrystalline graphene has an inherent tendency to buckle, i.e. develop out-of-plane, three-dimensional structure. A force applied to stretch a piece of polycrystalline graphene…
Rupture of amorphous graphene via void formation
Sandeep K. Jain, Gerard T. Barkema
Apart from its unique and exciting electronic properties, many sensor based applications of graphene are purely based on its mechanical and structural properties. Here we report a…
Structural characterization of carbon nanotubes via the vibrational density of states
Albert J. Pool, Sandeep K. Jain, Gerard T. Barkema
The electrical and chemical properties of carbon nanotubes vary significantly with different chirality and diameter, making the experimental determination of these structural prope…
Probing the Shape of a Graphene Nanobubble
Sandeep K. Jain, Vladimir Juricic, Gerard T. Barkema
Gas molecules trapped between graphene and various substrates in the form of bubbles are observed experimentally. The study of these bubbles is useful in determining the elastic an…
