Webseamless CNT-graphene heterostructures [70] 36, (figures 1(d) and (e)). Multilayered vertical CNT-graphene heterostructure was also reported as an all-carbon pillared structure [71] (figure (f)), in which 1 graphene was used as the platform for CNT growth and the grown CNTs served as pillars to support graphene layers. Webconsider it to be unexpected that rather a short-time exposure of graphene to the low or medium-energy e-beams results in such damage. The reported Raman spectroscopy measurements indicate substantial damage to the single-wall CNTs for the low-energy e-beam dose of ~ 8 x 1017 e/cm2 [26]. Similar effects were observed for CNTs even with
