Abstract Scope |
Silicon nanocrystals (Si-NCs) have been extensively studied for about three decades since they exhibit an intense red light emission induced by the quantum confinement of carriers allowing radiative recombination much more efficiently than in bulk silicon. Despite many efforts, a full efficient silicon based optoelectronics is not yet available. Moreover, the emission wavelength range remains limited. Doping Si-NCs is an alternative way to render Si-based materials optically active and to obtain a wide wavelength range. In this work, rare-earth doping as well as phosphorus and boron doping were investigated. Thin films were obtained by e-beam assisted evaporation under ultra-high vacuum. The emission properties of the doped materials will be discussed in relation with the chemical content, localization of dopants and structural characterization at the nanoscale. Some applications in relation with solar cells, plasmonics or sensors will be presented. |
