Semiconductor nanocrystals can be used as quantum dots to produce band gap engineering by varying the nanocrystals size, which is a very interesting property for optoelectronic components. This work is dedicated to the creation of doped silicon nanocrystals embedded in SiO2 and binary (InAs and GaAs) and ternary nanocrystals of InxGa1-xAs embedded in Si and also to investigate their structural, electrical and optical properties. Ion beam synthesis allows a control of the nanocrystals amount and size. Structural characterizations were able to demonstrate the doping of silicon nanocrystals with phosphorus and arsenic at an average atomic concentration of 8 %. We have also shown the ability to modulate the size and the chemical composition of ...
