Wafer scale epitaxial graphene transfer |
摘要 |
A method for transfer of a two-dimensional material includes forming a spreading layer of a two-dimensional material on a substrate, the spreading layer having a monolayer. A stressor layer is formed on the spreading layer, and the stressor layer is configured to apply stress to a closest monolayer of the spreading layer. The closest monolayer is exfoliated by mechanically splitting the spreading layer wherein the closest monolayer remains on the stressor layer. |

1. A method for transfer of a two-dimensional material, comprising:
forming a spreading layer of a two-dimensional material on a substrate, the spreading layer having at least one monolayer; forming a stressor layer on the spreading layer, the stressor layer being configured to apply stress to at least a closest monolayer of the spreading layer; exfoliating at least the closest monolayer by mechanically splitting the spreading layer into portions wherein at least the closest monolayer remains on the stressor layer; transferring at least the closest monolayer on the stressor layer; and etching away the stressor layer to release at least the closest monolayer onto a second substrate for device formation. |
