Abstract
A transparent conductor comprising: a graphene layer and a permanent dipole layer on the graphene layer configured to electrostatically dope the graphene layer.
Claims18
A transparent conductor comprising:
- a graphene layer, and
- a permanent dipole layer on the graphene layer configured to electrostatically dope the graphene layer, wherein the permanent dipole layer being polarised and which maintains its dipole orientations without any applied electric field, wherein the permanent dipole layer is formed from a material comprising at least one of polar molecules or ions, and wherein the dipoles of the material are aligned to create the polarised permanent dipole layer.
A method of fabricating a transparent conductor comprising
- forming a wafer or sheet of graphene,
- electrostatically doping the graphene with a layer of permanent dipoles, the layer being a layer of polarisable material, and
- polarising the layer of polarisable material such that the layer of polarisable material maintains its dipole orientations without any applied electric field.
