Scattering power P(Q), equation (2), obtained by PDDF calculation in virtual NPs of silicon. (a) Spherical NPs of diameter D, ranging from 1 to 90 nm, and (b) cubic NPs of edge L, ranging from 1 to 70 nm. An RMS displacement of 1.4 pm mimics vibrational disorder at all atomic sites in the NPs. The insets show examples of spherical (D = 20 nm) and cubic (L = 16 nm) virtual NPs with ∼200 000 atoms each. |
