Abstract

The (Ga,Mn)N nanowires with different Mn concentrations of 0.5%–10% were synthesized by varying the separation between MnCl2 and GaN powders under NH3 gas flow via the chemical vapor deposition method. The structural analyses demonstrate that all the nanowires are a single crystal without secondary phases. The room-temperature ferromagnetism was found to depend on Mn concentration in the (Ga,Mn)N nanowires which were converted from n type to p type with increasing Mn concentration. In particular, the highest magnetic moment was shown in the p-type (Ga,Mn)N nanowires with Mn concentration of 5% and hole concentration of 1017cm−3.
