Crystal doping

WebA dopant (also called a doping agent) is a trace of impurity element that is introduced into a chemical material to alter its original electrical or optical properties. The amount of … WebMar 21, 2024 · A crystal with an added dopant is referred to as an extrinsic semiconductor or doped material. The amount of impurity added is generally small, perhaps in the neighborhood of one part per million. The dopant may be added through a gaseous diffusion process where the crystal is heated in an oven and the dopant added in gaseous form.

WebApr 10, 2024 · We have studied the effects of the doping of FPs in U or C vacancies on the mechanical properties of UC. For the doping in the U vacancy, we find that the doping of all FPs except He increased the C 11, C 44, B, G, and E of U 1-x C. Because the atomic radius of He is too small, it has little effect on the stability of UC crystal.
