我们提出了一个简单的模型来解释平行孪晶的形成机制，这是相关的硅面枝晶生长，并试图证实其有效性，通过原位观察。该模型涉及到形成一个孪晶界面上的{111}小平面上的生长界面，然后形成另一个平行于第一个孪晶。随后，在该模型中，小面枝晶平行于小面平面生长。通过生长实验成功地观察到了这种生长行为。
We propose a simple model to explain formation mechanism of parallel twins that are related to Si-facetted dendrite growth, and attempt to confirm its validity by in situ observations. The model involves the formation of a twin boundary at the {111} facet plane on the growth interface followed by formation of another twin parallel to the first one. Subsequently, a facetted dendrite grows parallel to the facet plane in this model. This growth behavior was successfully observed by growth experiments.
