| Description | Selective deposition of chalcogenides like WS2 and MoSe2 by electrodeposition has been demonstrated. Lateral growth on the surface is typically 50 times that of vertical growth, which is ideal for the production of 2D materials, and it is even possible using 2D electrodes made from graphene as the nucleation centre. We have also made heterojunctions between two different materials deposited at different electrodes. There are some really exciting possibilities for this technique since it has some unique advantages - e.g. site-specific deposition in geometries that cannot be achieved by other methods, self-limiting growth, and it is scalable to a high throughput manufacturing process. However the as-deposited material is amorphous, requiring an anneal to be transformed into the crystalline material we really want. |
| Exploitation Route | The chemical design of the salt+electrolyte system, i.e. ensuring that the salt splits into the deposited compound and a residue that is simply the electrolyte, is an elegant method to avoid unwanted byproducts and contamination in electrodeposition, and will have widespread applications. |
