Abstract

We present a new type of (In_1-xMn_x)As DMS QD (quantum dot) which successfully grown by using MBE and whose Tc, was above room temperature. A high-resolution TEM image shows that the formed (In_1-xMn_x)As QDs are single crystals without defects, dislocations, or stacking faults, and this behavior is similar to the typical self-assembled III-V QDs. The average width of the (In_1-xMn_x)As QDs is approximately 60 nm. The EDX spectrum demonstrates that the stoichiomehy of the QDs is (In_1-xMn_x)As and that the ratio between the In and the Mn compositions is 84:16.
