nanoCVD-WPG

A compact, plasma-enhanced, wafer-scale CVD (Chemical Vapour Deposition) system for rapid synthesis of high-quality graphene.

Techniques:

Applications include: Graphene & 2D materials, Electrodes for photovoltaics, Touchscreen displays, High-performance electronics Biological, chemical and mechanical sensors, Electrical energy storage

Developed in collaboration with academic partners, nanoCVD technology is proven for the rapid throughput production of high-quality graphene for R&D applications via the well-established chemical vapour deposition (CVD) route that is considered most promising for future commercialisation of graphene-based technologies.

Model nanoCVD-WGP is the result of the scaling of this technology to the wafer scale (3” or 4”), together with the addition of plasma-enhanced capability in a cold-walled chamber. While this represents a significant leap in the capabilities of the nanoCVD range, intelligent design means the compact nature of the units has been maintained for efficient location and integration.
