Si_(1-x)Ge_x alloy is a complete solid solution and has almost the same valence electron density with pure Si. Meanwhile, the adding of Ge atom in alloy has small affect on the valence electron densities of C_iC_s and C_iO_i defects.
Si_(1-x)Ge_x合金是一种完全固溶体,其价电子密度分布与纯Si体系几乎相同,且Ge的加入对C_iC_s缺陷和C_iO_i缺陷的价电子密度分布影响也很小。

We solve this problem by a quantity called the average valence electron energy.
我们通过一个叫做平均价电子能的量来解决这一问题。
Chlorine has a high valence electron energy.
氯的价电子能很高。
These have low average valence electron energies.
他们有较低的平均价电子能。
if we're actually thinking about electron configuration and we look at lithium, sodium and potassium, these all have one valence electron.
让我们来想一想,锂,钠,钾的电子排布,它们都只有一个价电子。
And, at the other extreme, we have elements with very high value, elements with high average valence electron energy.
另外,在另一端,我们有原子序数较大的元素,这些元素有着较高的平均化合价和电子能。
OK, elements with low average valence electron energy, and here I'm saying below 11 electron volts, these are good electron donors.
平均价电子能都较低的元素,我是指那些低于11电子伏的,这些是很好的电子给体。
