ABSTRACT
We present observations of optical second-harmonic generation (SHG) from silicon nanocrystals embedded in SiO[sub 2]. SHG sensitivity to Si/SiO[sub 2] interface states, charge on the nanocrystals, and particle density gradients is demonstrated. SHG is proven to be a powerful noncontact nondestructive diagnosis tool for characterization of Si-nanocrystal-based devices and materials. © 2001 American Institute of Physics.
