This application was originally filed as PCT Application No. PCT/FI2016/050550 filed Aug. 5, 2016 which claims priority benefit from EP Patent Application No. 15182976.9 filed Aug. 28, 2015.

Examples of the disclosure relate to a method for forming apparatus comprising two dimensional material. In particular, they relate to a method for forming electronic apparatus comprising a two dimensional material such as graphene.

Apparatus comprising two dimensional materials such as graphene are well known. For instance graphene can be provided in devices such as resistive sensors or field effect transistors to enable parameters such as chemicals or light to be detected. In other devices graphene field effect transistors can be used as logic elements or other electronic components.

It is useful to provide improved methods of forming such devices.

According to various, but not necessarily all, examples of the disclosure there may be provided a method comprising: forming a layer of two dimensional material on a first release layer; forming at least two electrodes; forming a second release layer overlaying at least a portion of the layer of two dimensional material; providing mouldable polymer overlaying the at least two electrodes and the second release layer; and removing the first and second release layers to provide a discontinuity between the mouldable polymer and the layer of two dimensional material.

In some examples the discontinuity may set the layer of two dimensional material and the mouldable polymer apart from each other.
