Carbon nanotubes and graphene towards soft electronics …

25/4/2014· Although silicon technology has been the main driving force for miniaturizing device dimensions to improve cost and performance, the current appliion of Si to soft electronics (flexible and stretchable electronics) is limited due to material rigidity. As a result, various prospective materials have been proposed to overcome the rigidity of conventional Si technology. In particular, nano
