摘要
只提供摘要形式。在本文中，我们描述了(In,Mn)作为自组织量子点或“稀释磁量子点”(DMQD)的生长，Mn含量高达5%，衬底温度为285/spl℃。研究了量子点层的铁磁特性。在含5% Mn的(in,Mn) as QD层中，测得T/sub / c/高达150k。描述了使用DMS或DMQD层作为自旋对准器的自旋极化量子点表面发光led的特性。
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.
