Molecular formula : CAS :
nature : also known as the composite. (1) growth of free radicals by combining two formed a macromolecule saturated termination reaction, as the light. (2) by the semiconductor electronic role-excitation from the valence band to the conduction band, creating an electron-hole pair, the solid surface may be passed "composite Center" captured a minority-carrier and the majority of Carrier, resulting in electron-hole pairs of disappeared, to achieve stability, the process known as the composite.
