Abstract
Official abstract text for this publication.
An apparatus and method, the apparatus including a charge carrier wherein the charge carrier includes a continuous three dimensional framework including a plurality of cavities throughout the framework; sensor material provided throughout the charge carrier; wherein the sensor material is configured to transduce a detected input and change conductivity of the charge carrier in dependence of the detected input.
First claim
Opening claim text (preview).
We claim: 1. An apparatus comprising: a charge carrier, said charge carrier having a continuous three-dimensional framework with a plurality of cavities distributed throughout, said continuous three-dimensional framework including a plurality of layers of graphene, said continuous three-dimensional framework being formed from a foam of said plurality of layers of graphene, said plurality of cavities being located within said foam; and sensor material disposed at least within said cavities, the sensor material being capable of detecting an input from outside the charge carrier and of changing a conductivity of the charge carrier in response to the detected input, wherein the sensor material comprises quantum dots. 2. The apparatus as claimed in claim 1 wherein the continuous three-dimensional framework of the charge carrier is formed from a two-dimensional material, each of said layers of graphene being the two-dimensional material. 3. The apparatus as claimed in claim 2 wherein the two-dimensional material forms boundaries of the plurality of cavities. 4. The apparatus as claimed in claim 1 wherein the charge carrier conducts charge in any direction. 5. The apparatus as claimed in claim 1 wherein the input includes incident electromagnetic radiation. 6. The apparatus as claimed in claim 5 wherein the incident electromagnetic radiation includes X-rays. 7. The apparatus as claimed in claim 1 wherein the input includes a change in temperature. 8. The apparatus as claimed in claim 1 wherein the input includes pressure. 9. The apparatus as claimed in claim 1 wherein the input includes a change in shape of the sensor material. 10. The apparatus as claimed in claim 1 wherein the charge carrier is disposed on an insulating substrate. 11. The apparatus as claimed in claim 1 wherein the charge carrier is disposed between two electrodes. 12. A transistor comprising the apparatus as claimed in claim 1 . 13. The transistor as claimed in claim 12 wherein the transistor is a thin film transistor. 14. A method comprising: providing a charge carrier, said charge carrier having a continuous three-dimensional framework with a plurality of cavities distributed throughout, said continuous three-dimensional framework including a plurality of layers of graphene, said continuous three-dimensional framework being formed from a foam of said plurality of layers of graphene, said plurality of cavities being located within said foam; and disposing sensor material at least within said cavities, the sensor material being capable of detecting an input from outside the charge carrier and of changing a conductivity of the charge carrier in response to the detected input, wherein the sensor material comprises quantum dots.
