| Research Abstract |
Diluted magnetic semiconductors which display both semiconducting and ferromagnetic properties have attracted considerable research interest as new functional device materials. As a new diluted magnetic semiconductor, vanadium-doped ZnSe is theoretically predicted to induce ferromagnetism above room temperature. Vanadium-doped ZnSe was epitaxially grown on (100) GaAs substrate by metal-organic vapor phase epitaxial method in an atmospheric pressure. We investigated the effects of vanadium doping on the crystal structure of ZnSe, as well as the optical and magnetic properties of vanadium-doped ZnSe. Vanadium-doped ZnSe(0.2at%) film fabricated under the epitaxial growth condition showed superparamagnetic behavior at room temperature.
