Characterization of the crystallographic characteristics of the Si/CNTs nano-network was accomplished by X-ray diffraction (XRD) (Panalytical Xpert Pro). Various peaks that can be seen in Fig. 1a at 2θ of 28.68, 47.48 and 56.28° correspond to the usual peaks of crystalline silicon (111), (220) and (311) crystal planes.
