Quantum Materials & Device Integration

From quantum materials to integrated devices.

Nova supports research that combines diamond with SiC, hBN, graphene and other quantum-material platforms. Material selection, defect engineering, precision processing and device geometry can be coordinated around the final photonic, microwave, electronic or hybrid architecture.

Diamond / NVSiChBN / GrapheneHybrid Devices
Integrated quantum device stack combining graphene, hBN, photonic and microwave structures, NV diamond and SiC
Multiple material platforms

Diamond, SiC, hBN, graphene and related quantum materials can be considered within one device concept.

Precision fabrication

Cutting, polishing, thinning, custom geometry and other post-growth processing can be matched to integration requirements.

From materials to devices

Material engineering can be coordinated with implantation, processing, characterization and collaborative device development.

Integration Strategy

The interfaces matter as much as the materials.

Hybrid quantum devices depend on more than choosing the right substrate. Surface quality, layer placement, optical access, electrode geometry, crystal orientation and mechanical tolerance can all determine whether the integrated system works as intended.

01 · MATERIAL STACK

Select the quantum function of each layer

Diamond can provide engineered NV centers, while SiC, hBN, graphene or other materials can support complementary optical, electronic or defect-related functions.

02 · DEFECT / INTERFACE ENGINEERING

Prepare the active region deliberately

Implantation, annealing, surface preparation and characterization can be incorporated when the device requires controlled defects or engineered interfaces.

03 · DEVICE GEOMETRY

Design around the final structure

Thickness, small-sample fabrication, side polishing, custom shapes, orientation control and precision processing can be matched to the photonic or microwave architecture.

Typical directions: diamond–2D-material heterostructures, diamond/SiC hybrid systems, on-chip microwave and photonic structures, custom sensor devices and research-specific multi-material stacks.
Material Solutions

Choose the platform around the device function.

Nova’s core strength remains quantum diamond, while SiC, hBN, graphene and other emerging systems are supported as custom or collaborative research platforms.
