Numerical investigation on mechanical properties of graphene covering silicon nanofilms Original Research Article Computational Materials Science, Volume 126, January 2017, Pages 321-325 Yunqing Tang, Bing Yang, Haiying Yang, Ping Yang, Jianming Yang, Yongle Hu
Graphical abstractThe size effect of structural evolution on graphene covering silicon nanofilms is explored. We investigated the deformation process of the composite film under uniaxial tensile loading. We discussed the structural failure mode of graphene covering silicon nanofilms. We find the size effect of thickness on the strength is significant at the thickness less than 4nm. We detect the 1nm thick film has significantly better mechanical properties due to its different structural failure mode. It implies the findings will be helpful for applications of graphene in silicon-based devices.

| Aligning graphene sheets in PDMS for improving output performance of triboelectric nanogenerator Original Research Article Carbon, Available online 19 October 2016, Pages Xiaona Xia, Jie Chen, Guanlin Liu, Muhammad Sufyan Javed, Xue Wang, Chenguo Hu
Graphical abstractThe TENG based on aligned graphene sheets embedded in PDMS has been fabricated by repeated spin-coating technique, which has the higher breakdown voltage and lower dielectric loss owning to the oriented distribution of graphene sheets and excellent output performance.Image 1
