The acceptor atoms are required to have one less valence electron than the semiconductor.

受主原子必须比半导体元素少一价电子.

Hole - Similar to a positive charge, this is caused by the absence of a valence electron.

空穴 - 和正电荷类似, 是由缺少价电子引起的.

On the basis of the principle, the OET (orbital-energy topological index) was proposed by revising the valence electron distance matrix with the orbital energy.

根据该原理，利用价电子轨道能量对价电子距离矩阵进行修正。

The doublet nature of this and other lines in the Na spectrum indicates a doubling of the expected number of states available to the valence electron.

钠光谱中的这条线以及其它线的双重性指出预期价电子可用的状态数是双重的。
