Growth of CrNx films by DC reactive magnetron sputtering at constant N2/Ar gas flow

Chromium nitride coatings have been deposited on silicon by magnetron sputtering in an Ar + N2 atmosphere at different bias substrate voltages. The poisoning effect has been studied monitoring the discharge voltage and total pressure. The chemical composition and crystalline structure have been anal...
