ELECTRICALLY CONNECTED GRAPHENE-METAL ELECTRODE DEVICE, AND ELECTRONIC DEVICE, ELECTRONIC INTEGRATED CIRCUIT AND ELECTRO-OPTICAL INTEGRATED CIRCUIT USING SAME

摘要

An device according to the present invention comprises: graphene; and a metal electrode, the metal electrode and the graphene being electrically connected, the following relationship of Eq. (1) being satisfied:; $$ \begin{array}{cc}\coth \left(\sqrt{\frac{r_{\mathrm{GP}}}{r_C}}S\right)1.3,& \mathrm{Eq}.\left(1\right)\end{array}$$ ;where r_GP (in units of Ω/μm²) denotes the electrical resistance of a graphene layer per unit area, r_C (in units of Ωμm²) denotes the contact resistance per unit area between the graphene layer and a metal electrode, and S denotes the contact area (in units of μm²) between the graphene layer and the metal electrode.
