Diamond Growth on Unconventional Substrates

Diamond Growth on Unconventional Substrates ID: 2022-039

A revolutionary method for growing diamonds on unconventional substrates using diamond powder to mitigate thermal expansion mismatches.

Technology Overview:

This innovative technology outlines a method for diamond growth that leverages a loose layer of diamond powder or grit, enabling the formation of a single, cohesive diamond structure without the limitations posed by traditional solid substrates. It supports the development of various diamond types, including both high-purity and doped diamonds, and is versatile across different gas mixtures and reactor types, such as hot filament, direct current, and microwave plasma reactors. The process is designed for scalability, allowing for potentially large growth areas and compatibility with existing diamond growth techniques for enhanced functionalities.
