F.; Lee, W. N.; Huang, J. H.; Chin, T. S.; Huang, R. T.; Chen, F. R.; Kai, J. J.; Aravind, K.; Lin, I. N.; Ku, H. C.淡江大學物理學系American Institute of Physics (AIP)Journal of Vacuum Science & Technology B 23(4), pp.1376-1378Self-assembled In0.79Mn0.21As quantum dots were successfully grown on GaAs (001) substrates by low-temperature molecular beam epitaxy. Atomic force microscopy and high-resolution transmission electron microscopy confirm the formation of quantum dots. High-resolution lattice image suggests that In0.79Mn0.21As dots are single phase with zinc-blend structure. The dots exhibit typical ferromagnetic state at 5 K and demonstrate a Curie temperature of similar to 290 K which is much higher than those of (In, Mn)As diluted magnetic semiconductor alloys ever reported. The significant increase in Curie tempera
