▎ 摘　　要

NOVELTY - The electronic device has a graphene layer (103) that is formed on substrate (101) which is provided with a step-difference portion (102). A barrier portion (132) of graphene layer is formed in flat portion (131) of recessed portion of step-difference portion. A carrier injection region (133) is formed in flat portion (134) of convex portion of the step-difference portion. The current flowing through the graphene layer is determined from the signal of probe (105) which is contacted to convex and recessed portions of the step-difference portion. USE - Variable resistance electronic device. ADVANTAGE - The performance efficiency of the electronic device can be improved by forming the graphene layer and the current through the graphene layer can be determined with high precision. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the electronic device.
