查询词典 acceptor doping

With the Eu doping level increased to more than 1mol%, the content of B-site occupancies is increased and acceptor doping is to be dominant.

当Eu含量低于1mol％时，Eu在PZT晶格中主要占A位，起施主掺杂作用；随着Eu含量的增加，其在PZT晶格中占据B位的比例逐渐增多，受主掺杂作用逐渐增强。

In contrast, the concentration of deep defects is very low in annealed undoped InP and the doping of Fe acceptor by diffusion acts as the only compensation centre to pin the Fermi level, resulting in excellent electrical performance.

相比之下，非掺退火半绝缘InP材料中深能级缺陷浓度很低，通过扩散掺入的铁受主作为唯一的补偿中心钉扎费米能级，因而表现出优异的电学性质。

On the respect of piezoelectric properties, Mn coexisted as Mn〓 and Mn〓 in PZNPZT system and suitable Mn doping as acceptor improved Q〓 and lowed tan δ greatly, meanwhile, high density assured K〓 out of decrease.

适量的锰掺杂使PZN-PZT体系的机械品质因数Q〓上升和介电损耗tan δ下降，同时瓷体较高的致密度又保证了机电耦合系数K〓不致降低。

It was shown that the improvement of electric properties in 1%Eu-PZT can be attributed to Eu donor doping, which decreases the concentration of defects such as oxygen vacancies and holes, while the degradation in fatigue and leakage current properties shown in the films with more than 1mol% Eu dopant results from the apparently dominant acceptor doping, which increases the concentration of oxygen vacancies and holes.

结果表明，1mol％Eu施主掺杂，可以减少氧空位以及空穴等缺陷浓度，因此1％Eu-PZT薄膜的极化疲劳和漏电流特性得到明显改善；高于1mol％Eu的受主掺杂作用使薄膜中氧空位以及空穴等缺陷浓度增加，导致PZT薄膜电学性能恶化。

Moreover, as Q〓 had close relation with voltage step-up ratio and working stability of piezoelectric transformer, improving Q〓 was essential, which could be realized with acceptor doping or Pb O〓, Pb O〓 addition.

另外，添加PbO〓、PbO〓这类大功率组元也可以大幅度提升Q〓。

It can be easily doped high-quality n-type, but it is difficult to dope p-type. ZnO has largely failed to live up to its potential due to its "asymmetric doping" limitation, such as self-compensation, deep acceptor level, and low solubility of the acceptor dopants.

高质量的n型ZnO很容易实现，但是ZnO的p型掺杂由于其固有的极性却非常困难，这主要是因为ZnO中本征缺陷具有强烈的自补偿，受主元素在ZnO中多为深能级并且固溶度较低。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
