Description: 
By means of the effective mass approximation we have computed without any adjustable parameters the energy levels and hyperfine splitting of a P impurity in silicon spherical nanocrystals as a function of the nanocrystal radius. Confinement effects produce an enhancement of the energy levels and of the hyperfine splitting as the crystal radius is decreased. Our results are in good agreement with available experimental data.
