| Description | The project developed a scalable method for integrating transition metal dichalcogenides (TMDCs) onto graphene, creating heterostructures with promising electronic and optoelectronic properties. A key achievement is the controlled deposition of various TMDCs onto graphene, coupled with an understanding of the interface and defect formation. Furthermore, the project has also revealed the electronic properties and charge transport mechanisms within these heterostructures. These findings have been validated through the fabrication of high-performance photodetectors, demonstrating the potential of this approach for next-generation devices. |
| Exploitation Route | This EPSRC project has put the basis for a scalable process of fabricating TMDCs on graphene, thoroughly investigated the structural, electrical, and optical properties of the resulting heterostructures, and demonstrated their potential in device application. These outcomes provide a foundation for future research and development, enabling others to build upon our findings and develop new device applications. Specifically, the project's outputs can be taken forward and put to use by others in the following ways: * Scalable manufacturing platform: This project's key achievement is developing a foundational process for the scalable fabrication of TMDCs on graphene. This process is crucial for translating laboratory-scale demonstrations into industrially relevant manufacturing processes. * Driving application development: The characterisation of structural, electrical, and optical properties and the successful demonstration of device applications provide researchers and industry with critical data and insights. This data can help to optimise the heterostructures to develop a range of device applications including low-power electronic devices, photonic devices, and potential integration in quantum devices. * Extending to a Broader Range of 2D Materials: The scalable process developed in this project is not limited to TMDCs. It can be extended and adapted for the deposition of other 2D materials onto graphene, creating a versatile platform for exploring a wide range of heterostructures and their potential applications. This adaptable methodology will be of significant value to material scientists and engineers working with 2D materials beyond those studied in this project. |
