1.Why do we need silicon and germanium materials?

    Material is a milestone in the history of human evolution, an important pillar of modern civilization, the foundation and development of high-tech leader.In all materials, we can not fail to mention plunging us into the information age is now the first hero - semiconductor materials.Silicon  and germanium  is a major semiconductor materials, including silicon is accounted for more than 90% of the share of semiconductor materials,Both in the metallurgical, chemical, energy, military, aerospace and other fields have a wide range of uses.For example, Silicon metal is widely used in iron and steel, aluminum, organic chemical industry, Polysilicon used in solar photovoltaic industry, Monocrystalline silicon used in IC industry, Germanium dioxide used in the catalyst, Germanium crystal solar cells used in satellites, Germanium as a night-vision lens used in fighter planes.so, We need to silicon and germanium materials.
