Abstract: Abstract:Self-assembled In1−xMnxAs quantum dots (0.19 ⩽ x ⩽ 0.45) have been grown on GaAs (100) substrates by low-temperature molecular beam epitaxy. The microstructure analysis revealed that the uniformly distributed In1−xMnxAs dots have a zinc blende structure as x ⩽ 0.38. Furthermore, all samples exhibit ferromagnetic state at 5 K, and their Curie temperatures range from 260 to 340 K varying with x. These (In, Mn)As quantum dots are promising for room-temperature spintronic devices.
