Strong increase in electrical conductivity of graphene oxide (GO) (I ≈ 10⁻⁹ A) is found by addition of Ni nanoparticles (NiNPₛ) preliminarily solved by HCl (Niₛₒₗ) (I ≈ 10⁻⁴ A) or powder (Niₚₒw) obtained from this solution (I ≈ 10⁻⁶ A), while simply mixing GO with NiNPₛan insulator similar to pure GO is obtained. Thus, Niₛₒₗand Niₚₒwcan be used to transform GO from insulator to semiconductor. One ...
