Crystal doping

WebIn this work, a concentration-gradient niobium-doping strategy was applied to modify the single-crystal LiNi 0.83 Co 0.12 Mn 0.05 O 2 cathode, with Nb concentration decreasing linearly from the surface to the core of the particle. As a result, the Nb-rich surface functions as an electrochemically active protective layer against electrolyte ... 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.
