Ge nanocrystals (Ge-ncs) were produced by implantation of {sup 74}Ge{sup +} into a SiO{sub 2} film on (100) Si, followed by high-temperature annealing from 700 °C to 1100 °C. Transmission electron microscopy (TEM) studies show that the average size

Samples containing silicon nanocrystals (Si-nc) with radius of approximately 3 nm embedded in SiO2 exhibit a strong PL emission around 750 nm because of the quantum confinement of the exciton inside the Si-nc. To characterize the contribution of abso

The photoluminescence (PL) spectra of silicon nanocrystals (Si-nc) produced by Si+ implantation in SiO2 are modulated by interference effects associated with the thickness of the SiO2 layer and the depth where the Si-nc are situated. A model based on

In this paper, we report on the design of two major components of a laser architecture using Si-nc embedded in SiO2 as the optical gain medium and sub-wavelength periodic structures to form the resonant cavity. Dimensions of the structures have been

Implantations of pure 28Si+, 29Si+, and 30Si+ into SiO2 can provide significant insight into the formation of silicon nanocrystals (Si-nc) and their light emission properties. Si-nc produced with different fractions of the heavier Si isotopes have be

The injection of current in electroluminescent devices based on silicon nanocrystals (Si-nc) embedded in SiO 2 matrix is facilitated by the use of very thin SiO 2 layer. Therefore, the production of Si-nc by implantation of excess Si ions in the SiO
