One-pot synthesis of Mn3O4-decorated GaN nanowires for drastic changes in magnetic and gas-sensing properties
Novel composite nanowires have been synthesized with Mn3O4 structures being coated on the surface of the GaN nanowires. The addition of Mn3O4 shell nanostructures significantly enhanced the gas-sensing sensitivity. The addition of Mn3O4 shell turned the n-type sensing characteristic of the pure GaN nanowires into the p-type one. The presence of Mn3O4 provided an acceptable ferromagnetic ability.
