Towards growth single crystal diamond

项目摘要

This is a proof of concept project to find the optimum conditions required to grow singlecrystal diamond on a seed crystal from a liquid carbon source using Designed Materials' proprietary low pressure/high temperature diamond growth process. At present, there are several high value industry sectors where large single crystal diamond substrates would be highly desirable but are currently expensive to access (e.g. aerospace, defense, power electronics). The aim of the project is therefore to scope the ability of this process to grow diamond substrates from seed crystals reliably and reproducibly, and in formats that would suit potential end users. The knowledge gained from this project will be used to produce designs for a prototype reactor that can grow single crystal diamond substrates at size and format that addresses at least one high value industrial application.The project is innovative because it looks to offer several advantages over the current state of the art Chemical Vapour Deposition (CVD) methods of growing single crystal diamond.Firstly, the process uses relatively cheap feedstock materials and has lower basic energy requirements than CVD. Secondly, it has the potential to be more scalable than current CVD, potentially growing larger sized substrates. Finally, it can deliver much higher concentrations of carbon atoms to the growth surface than

这是一个概念验证项目，旨在找到使用Designed Materials专有的低压/高温金刚石生长工艺从液态碳源在籽晶上生长单晶金刚石所需的最佳条件。目前，有几个高价值的工业部门，其中大单晶金刚石基底是非常理想的，但目前使用起来很昂贵（例如航空航天、国防、电力电子）。因此，该项目的目的是确定该工艺的能力范围，以可靠和可重复的方式从籽晶中生长金刚石衬底，并以适合潜在最终用户的形式。从该项目中获得的知识将用于生产原型反应器的设计，该原型反应器可以生长单晶金刚石衬底，其尺寸和格式满足至少一种高价值的工业应用。该项目是创新的，因为它看起来比目前最先进的化学气相沉积（CVD）生长单晶金刚石的方法提供了几个优点。首先，该方法使用相对便宜的原料，并且具有比CVD更低的基本能量需求。其次，它有可能比目前的CVD更具可扩展性，可能生长更大尺寸的衬底。最后，它可以向生长表面提供比纳米碳更高浓度的碳原子。
