Geometrical Effect Explains Graphene Membrane Stiffening at Finite Vacancy Concentrations
Zhigong Song, Zhiping Xu
The presence of defects such as vacancies in solids has prominent effects on their mechanical properties. It not only modifies the stiffness and strength of materials, but also cha…
Mechanistic Transition from Phonon Propagation to Thermal Hopping in Two-Dimensional Solids
Yanlei Wang, Zhigong Song, Zhiping Xu
Thermal transport in solids changes its nature from phonon propagation that suffers from perturbative scattering to thermally activated hops between localized vibrational modes as…
Role of defects and geometry in the strength of polycrystalline graphene
Zhigong Song, Jian Wu, Zhiping Xu
Defects in solid commonly limit mechanical performance of the material. However, recent measurements reported that the extraordinarily high strength of graphene is almost retained…
Characterizing thermal conduction in polycrystalline graphene
Yanlei Wang, Zhigong Song, Zhiping Xu
Thermal conduction was explored and discussed through a combined theoretical and simulation approach in this work. The thermal conductivity k of polycrystalline graphene was calcul…
