Summary form only given. In this paper, we describe the growth of (In,Mn)As self-organized quantum dots, or "diluted magnetic quantum dots" (DMQD), with Mn content up to 5%, at a substrate temperature of 285/spl deg/C. The ferromagnetic properties of the quantum dot layers have been studied. A value of T/sub c/ as high as 150 K is measured in as-grown (In,Mn)As QD layers with 5% Mn. The characteristics of spin-polarized quantum dot surface emitting LEDs, using DMS or DMQD layers as spin aligners are described.
