Initially a flow of 500 sccm of Ar was introduced into the reactor after which the temperature was ramped to TN at 30°C/min under a flow of (I) 250 sccm of NH3, (II) 125 scmms of NH3 and (III) under different flows of NH3 and H2, but keeping the total flow constant at 200 sccm. Upon reaching TN, the same flows were maintained for 1 h at various temperatures (I), different nitridation times at 500 and 600°C (II) and for 1 h at 500°C (III).
