Abstract

A structure (200) for an electronic device, comprising: a patterned two dimensional material layer structure (Figure 1, 210') on a substrate (205); and a patterned dielectric layer (235") having (i) a first portion which is on and/or over the substrate adjacent an edge of the two dimensional material layer structure, and (ii) a second portion which extends from the first portion over the two dimensional material layer structure, and makes resting contact with a surface of the two dimensional material layer structure thereby defining a cavity (245) between at least the dielectric layer and the two dimensional material layer structure; wherein the dielectric layer has a thickness of less than 250 nm. The 2D material 210’ may be a monolayer of graphene, the substrate may be sapphire. Ther device may be a functionalised graphene based electrochemical biosensor.
