项目摘要

We realized vertical free-standing semiconducting nanowires (NW) hybridized with ferromagnetic MnAs nanoclusters (NC), which enables us to confine carriers one-dimensionally and control carrier spins, by utilizing our unique selective-area growth method. The dependences of MnAs NC formation on various NW templates were investigated. We observed that MnAs layers were grown on the top {111}B surface of InAs NWs with a diameter of about 80 nm, and into the host NWs from the side walls to form MnAs/InAs hetero-junctions, which enable us to realize spin-carrier injection to NWs, and in which most of the c-axes of hexagonal NiAs-type MnAs layers were approximately parallel to the <111>B directions of InAs NWs. We developed two-terminal device processes to realize spin-polarized light-emitting diodes. I-V characteristics of the prototype MnAs/GaAs hybrid NWs showed p-type conductivity possibly owing to thermal diffusion of Mn atoms into the host GaAs NW surfaces during the MnAs NC formation.
我们实现了与铁磁MNAS纳米群(NC)杂交的垂直独立式纳米线(NW)(NW),这使我们能够利用我们独特的选择性区域的生长方法,使我们能够一维载体和控制载体旋转。研究了MNAS NC形成对各种NW模板的依赖性。我们观察到,MNA层在inas nws的顶部{111} b表面生长,直径约为80 nm,并从侧壁进入主机nws,形成MNA/INAS杂音,这使我们能够实现Spin spin - 向NWS注入,其中大多数六角形NIAS型MNA层的C轴大约平行于INAS NWS的<111> b方向。我们开发了两端设备的过程,以实现自旋偏置发光二极管。原型MNA/GAAS杂交NW的I-V特性显示出P型电导率可能是由于MN原子在MNAS NC形成过程中将Mn原子的热扩散到宿主GAAS NW表面。
