它应该是一个电子的施主还是受主？
那么，相反地，如果它的电负性很低，它将会是一个电子的施主。
So, in contrast, if it has a low electronegativity, this then is going to be an electron donor.
控制施主浓度和掺杂等电子杂质，可以获得低吸收锗窗。
Germanium window with low absorption will be obtained through controlling donor concentration and doping isoelectronic im purity.
通过电子探针微区分析和霍尔效应法探测锗杂质及其相关施主和受主浓度的变化。
Electron probe microanalyses and Hall effect were used to measure the variations of Ge dopant and its related donor and acceptor concentrations.
结果表明，电子与施主离子间的距离不同，则极化势随施主离子位置的变化关系也不同。
It was found that, if the interval between the electron and the donor ion was different, the variation of polarization potential with the donor ion position z_0 in the PQW would be different also.
