▎ 摘　　要

NOVELTY - Making strip shaped graphene layer (10) involves: a1) providing graphene film (30) on surface of substrate (20); b1) adhering carbon nanotube structure (40) on graphene film, where carbon nanotube structure includes drawn carbon nanotube film (410) comprising carbon nanotube segments (411) parallel to each other and separated from each other by strip-shaped gap (412); c1) applying voltage to carbon nanotube film structure and adjusting temperature of substrate to remove parts of graphene film contacting carbon nanotube segments; and d1) separating nanotube structure with graphene layer. USE - For making strip shaped graphene layer used on the semiconductor devices such as sensors, transistors, solar cells, and thin film transistors. ADVANTAGE - The process of pulling/drawing ensures that a continuous, uniform, and free-standing drawn carbon nanotube film having predetermined width can be formed. DESCRIPTION OF DRAWING(S) - The figure shows cross-sectional view of method of making the strip shaped graphene layer.
