▎ 摘  要

NOVELTY - The method involves forming (21) first electrode portions on a substrate. A sheet of two dimensional materials overlaying at least part of the first electrode portions is provided (23). A second electrode portions are formed (25) on a superstrate. The superstrate is positioned (27) overlaying the substrate so that the second electrode portions are aligned with the first electrode portions. The substrate and superstrate are laminated (29) together so that the sheet of two dimensional material is positioned between the aligned first electrode portions and the second electrode portions. USE - Method for connecting two-dimensional (2-D) material such as graphene to electrodes and for sensing physical parameters such as electromagnetic radiation, chemicals or any other suitable parameters. ADVANTAGE - The method provides a better index matching for the electromagnetic radiation which improves the efficiency of the apparatus. The encapsulating layer prevents the fluid ingress or other chemicals from reaching the two dimensional material and degrading the performance of the two dimensional material. The method ensures that the two dimensional material has a high level of charge mobility and makes the apparatus more efficient. The method reduces the defects within the two dimensional material and increases the efficiency of the apparatus. The method removes the need for any patterning or lithography which improves the efficiency of apparatus. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an apparatus for connecting two-dimensional (2-D) material to electrodes. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for connecting two-dimensional (2-D) material to electrodes. Step for forming first electrode portions on a substrate (21) Step for providing two dimensional material (23) Step for forming second electrode portions (25) Step for positioning superstrate over the substrate (27) Step for laminating substrate and superstrate together (29)
