And you do this by changing the concentration of different dopants in the lattice spatially.

你通过在晶格中空间性地改变不同浓度来实现这一点。

Sorry nano systems more recent products incorporate elements other than carbon as with diamonds these dopants change a crystal's properties pure carbon diamonds are colorless.

抱歉，纳米系统近期产品中包含了以外其他元素，就像石一样，这些物会改变晶体性质，纯石是无色。

Defects, but you can intentionally replace a silicon atom with, say, a phosphorus atom, and then you can change the number of free electrons that are in a region of space that has that excess of what are called dopants.

缺陷， 但你可以有意用磷原子替换硅原子，然后你可以改变该区域中自由电子数量， 这个区域有过多所谓物。
