Mixed polarization in determining the film thickness of a silicon sphere by spectroscopic ellipsometry
《Chinese Physics B》2012年第1期147-152,共6页Zhang Ji-Tao Wu Xue-Jian Li Yan 
Project supported by the National Key Technology Research and Development Program of the Ministry of Science and Technology of China(Grant No.2006BAF06B06);the Tsinghua University Initiative Scientific Research Program,China(Grant No.2009THZ06057)
The effect of a spherical shape on the measurement result of spectroscopic ellipsometry (SE) is analyzed, and a method to eliminate this effect is proposed. Based on the simulation result of the SE measurement on a ...

Uncertainty reevaluation in determining the volume of a silicon sphere by spherical harmonics in an Avogadro project
《Chinese Physics B》2011年第9期152-158,共7页张继涛 吴学健 李岩 
Project supported by the National Key Technology Research and Development Program of the Ministry of Science and Technology of China (Grant No.2006BAF06B06);Tsinghua University Initiative Scientific Research Program,China (Grant No.2009THZ06057)
To determine the Avogadro constant with a target relative uncertainty of 2 x 10-s, the uncertainty component of the silicon sphere's volume introduced by the spherical harmonics method, which is usually used in deter...
