How free electrons are formed

Web17 dec. 2024 · Free radicals are formed naturally in the body as a byproduct of metabolism (oxidation). They can also be formed through external factors like smoking and pollutants. Let’s break down the... WebIt is free to move about the crystal lattice, not being bound to the Phosphorus lattice site. Since we have doped at one part phosphorus in 10 million silicon atoms, few free electrons were created compared with the numerous silicon atoms. However, many electrons were created compared with the fewer electron-hole pairs in intrinsic silicon.
