β¦ Synopsis
From experiments on photoluminescence in Si 3 N 4 the polaron energy of 1.4 eV was determined. This value is in agreement with the energy of thermal ionization determined from electron and hole transport. Quantum-chemical simulation showed that Si-Si bond is able to capture holes and electrons in Si 3 N 4 .

We developed an empirical potential for interactions between Si and N to describe silicon nitride systems using the Tersoff functional form. With this model, we explored the structural properties of amorphous silicon nitride through the Monte Carlo simulations and compared them to available experime
