Summary(II)<br />
The Raman scattering results reveal three Ramanactive<br />
modes, identified as E g, B 2g and A 1g. The<br />
intensity of certain modes depends on orientation of<br />
NCs and follows the selection rules. This indicates a<br />
possibility to determine the preferable growth<br />
direction of NCs under Raman investigations.<br />
The Raman peaks red shifts and the asymmetric<br />
broadening describe the trends due to phonon<br />
confined effect of the nanoscaled dimensions and<br />
residual stress.
