▎ 摘　　要

NOVELTY - The electronic component has graphene sheets (11,12) which are arranged to each other such that a bandgap serving boundary layer (19) is defined between the graphene sheets in a non-conductive state of the electronic component and an external electric field (E) is brought about in conductive state of component. The boundary layer is changed in the conductive state such that an electric current (I) flows between the graphene sheets. The graphene sheet (11) is arranged parallel to graphene sheet (12). The graphene sheets are electrically connected with the electrodes. USE - Electronic component e.g. FET, single-transistor logic gate such as NOT-AND (NAND) gate or XOR gate (all claimed) and graphene transistor. ADVANTAGE - The mass production solution for the use of graphene for electronic devices is achieved effectively. The manufacturing cost of transistor is reduced. The manufacture of the transistor is performed in simple manner. The size of the transistor is reduced and the efficiency of the transistor is improved. The high-performance transistors and logic gates are built efficiently. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for operating electronic component; and (2) a method for manufacturing electronic component. DESCRIPTION OF DRAWING(S) - The drawings show the top view of the graphene sheet, a sectional view of the superimposed layers of graphene in non-conductive state and a graphical representation illustrating the superimposed layers of graphene in conductive state.
