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.
