Abstract
Visible electroluminescence (EL) has been obtained from devices with active layers of silicon nanocrystals embedded in chlorinated silicon nitride (Si-nc/SiNx:Cl) thin films, deposited by remote plasma enhanced chemical vapour deposition, using SiCl4/NH3/H2/Ar. The active nc-Si/SiNx:Cl film was sandwiched between Al contacts and a transparent conductive contact of ZnOx:Al deposited by the pyrosol process. White EL centred at around 600 nm was observed, with a turn-on voltage of 5 V, and the intensity increasing as a function of voltage. Recombination between electron-hole pairs generated in the Si-nc by electron impact ionization is proposed as the EL mechanism.
