Maximum diameter (Ø) of Sn droplets (DPs) and SnxNyNWs obtained from heating up Sn under NH3and from the reaction of Sn + NH4Cl respectively, at different temperatures. In all cases a ramp rate of 30 °C/min was used to reachTGunder 250 sccm’s of NH3which was then maintained for a further 60 min at the growth temperature and after which the reactor was allowed to cool down to RT in a reduced flow of 50 sccm’s NH3
