▎ 摘　　要

NOVELTY - The electronic apparatus has a substrate, where a graphene sheet (23) is formed through a gate insulating film on the substrate. A source electrode is formed in an end of the graphene sheet, where a drain electrode is formed in another end of the graphene sheet. A gate electrode applies a gate voltage to the graphene sheet between a source region and a drain region, where a gate insulating film covers the graphene sheet between the source electrode and the drain electrode. A zigzag shaped edge part has a carbon atom, which comprises a bond, which is not bonded with another carbon atom. USE - Electronic apparatus for a top gate structure. ADVANTAGE - The gate electrode applies a gate voltage to the graphene sheet between a source region and a drain region, where a gate insulating film covers the graphene sheet between the source electrode and the drain electrode, and hence ensures forming a channel corresponding to the armchair end or a zigzag end in an efficient manner and forms a big conduction gap in the band structure of the graphene sheet. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the electronic apparatus. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic top view of an electronic apparatus. (Drawing includes non-English language text).
