研究了多晶硅定向凝固样品在生长过程中的晶粒取向和竞争。使用同步加速器x射线成像技术（射线照相和地形）对生长过程中晶粒结构的演变进行了原位和实时表征。此外，电子背散射衍射还揭示了晶粒的取向和孪晶关系。在生长过程中形成的新晶粒主要有两种来源：随机成核和孪生。结果表明，凝固后的试样主要由
Grain orientation and competition during growth has been analyzed in directionally solidified multicrystalline silicon samples. In situ and real-time characterization of the evolution of the grain structure during growth has been performed using synchrotron X-ray imaging techniques (radiography and topography). In addition, Electron Backscattered Diffraction has been used to reveal the crystalline orientations of the grains and the twin relationships. New grains formed during growth have two main origins: random nucleation and twinning. It is demonstrated that the solidified samples are dominated by
