The difference between monocrystalline silicon and polycrystalline silicon is that when molten elemental silicon solidifies, the silicon atoms are arranged into many nuclei in a diamond lattice, and if these nuclei grow into grains with the same orientation of the crystal plane, monocrystalline silicon is formed. If these nuclei grow into grains with different plane orientations, polysilicon is formed. The difference between polycrystalline silicon and monocrystalline silicon is mainly manifested in physical properties. For example, in terms of mechanical and electrical properties, polysilicon is inferior to monocrystalline silicon. Polysilicon can be used as a raw material for drawing monocrystalline silicon. Monocrystalline silicon can be regarded as the purest substance in the world, and general semiconductor devices require silicon with a purity of more than six 9s. The requirements for large-scale integrated circuits are even higher, and the purity of silicon must reach nine nines. It has been possible to make monocrystalline silicon with a purity of twelve nines. Monocrystalline silicon is an indispensable basic material in modern science and technology such as electronic computers and automatic control systems.
