Abstract
The present invention concerns new methods of fabricating a silicon material comprising phosphorus. The methods allow high levels of phosphorus to be combined with the silicon. In one aspect of the invention a sample of phosphorus is surrounded with a sample of silicon. At least some of the phosphorus is then vaporised and caused to interact with the silicon.
Claims8
A method for producing a composite material comprising phosphorus and silicon, the method comprising the steps:
- (a) taking a sample of phosphorus;
- (b) substantially surrounding the sample of phosphorus with a layer of silicon, the layer of silicon comprising a multiplicity of silicon particles;
- (c) applying heat to the silicon in such a manner that a temperature difference is established between at least part of the silicon layer and the sample of phosphorus, and in such a manner that at least some of the phosphorus is vaporised;
- and
- (d) allowing and/or causing at least some of the phosphorus vapour to contact at least part of the layer of silicon in such a manner that a molten composite material comprising silicon and phosphorus is formed.
