چکیده
|
First-principles calculation based on the gga methods has been applied to the prediction of the properties of bulk -uranium and seven -uranium surfaces. the number of layers in the slab has great effects on the simulated surface properties. the predicted surface properties are trustworthy when the slab number is nine or more. the surface energies of the seven low index uranium surfaces are in the range from 1.756 to 2.151 j/m2. the hybrid between the 5f orbital and 6d orbital also has somewhat impacts on the surface energies of uranium. © 2017 shan-qisong huang and xue-hai ju.
