单轴压应力 meaning in English

einachsige druckbeanspruchung uniaxial compression load

For strained si pmosfets , the hole mobility is not only determined by the tensity of strain , but also related to the strain types , which are uniaxial compressive strain and biaxial tensile strain . when electric field is high enough , the hole mobility will be deteriorated in pmosfets under biaxial tensile strain , however , in the case of uniaxial compressive strain , the deterioration will never occur
经模型分析发现,应变硅pmosfet空穴迁移率与应力作用方式有如下关系:当横向电场较高( > 5 105v / cm )时,双轴张应力作用下的应变硅pmosfet的空穴迁移率将发生退化,而单轴压应力器件则不会受到影响。
