van der Waals Heterostructures
Stack growth and stacking transfer of wafer-scale van der Waals superlattices and heterostructures.
Overview
What we study
Building wafer-scale van der Waals heterostructures by stack growth and stacking transfer of 2D crystals.
Starting from layer-uniform graphene and related films, we assemble graphene-based superlattices and superconductor heterostructures that keep clean interfaces at a scale compatible with integration.
- Methods
- Stack growth, stacking transfer, face-to-face transfer, interface characterisation
- Targets
- Wafer-scale graphene-based van der Waals superlattices and superconductor heterostructures
- Why it matters
- Clean, large-area stacks open routes from fundamental interface physics to integrated devices
Key questions
Where the science is heading
Stack growth and stacking transfer extend van der Waals assembly beyond small flakes, producing graphene-based superlattices over wafer-scale areas.
Controlled transfer and growth sequences minimise trapped residue and wrinkles so stacked layers retain intrinsic electronic quality.
Heterostructures and superconductor stacks combine complementary 2D layers, enabling interface states and device functions that a single crystal cannot provide.
