硅基薄膜的红光发射与纳米晶硅密度及波尔半径内晶粒数目有着密切的关系。
The red emission of Si-base films is related to the density of the nanometer grains and the number of the grains in the Bohr radius.
如果晶核的生成速度较快，而晶核生成后的成长速度较慢，则生成的晶核数目较多，晶粒较细。
If the generation of the nucleation rate faster, and crystal nucleus formation, growth speed is slow, it generated more cell number, grain is fine.
例如，葛峰的高度不随晶粒尺寸而变，而竹节峰的高度则与试样中所含的竹节晶界的数目成正比。
The height of the Ke peak is independent of the grain size while that of this peak is proportional to the number of the bamboo boundary containing in the specimen.
