| 摘 要： | ZnO稀磁半导体是目前最有希望集成到传统半导体中的一种新型材料，具有室温铁磁性能的ZnO稀磁半导体不仅可以大幅减小电子元器件的体积、提高集成密度，而且在传输效率上也有非常大的提升。目前，具有室温铁磁性能的ZnO稀磁半导体的制备方法可重复性差，且其磁性来源尚无统一理论解释。为了梳理不同实验方法制备出的ZnO稀磁半导体磁性能及其来源，本文对近10年来纯ZnO和Mn、Co单元素掺杂ZnO以及Mn、Co双元素共掺杂ZnO的制备方法、磁性能及磁性来源研究进行了综述，并认为:在制备过程中掺杂过渡金属离子对提升ZnO稀磁半导体室温铁磁性能有明显效果；在较低含量的Mn、Co掺杂ZnO体系中，可实现较稳定的室温铁磁性；要更好地理解磁性来源，必须从原子尺度通过理论计算与实验相结合的方式进行探索。

| Abstract: | ZnO dilute magnetic semiconductor (DMS) is a new kind of material, promising to be integrated into semiconductors. Meanwhile, ZnO DMS possessing the room temperature ferromagnetism (RTFM) could not only reduce the volume of electronic components and increase the integration density, but also improve the transmission efficiency greatly. At present, the preparing technology of ZnO DMS with the RTFM is poor in repeatability, and there is no unified theory to explain the magnetic origin. In order to sort out the magnetic properties of ZnO DMS prepared by different experimental methods and their origin, this paper has been reviewed the last 10 years investigations, including preparing technology, magnetic properties and magnetic origin of pure ZnO, Mn or Co and Mn-Co co-doped ZnO. And it is believed that the doping of transition metal ions in the preparation processing will improve the RTFM of ZnO DMS effectively. And the RTFM will be achieved stably in a lower content of Mn or Co doped ZnO systems. Besides, in order to better understand the origin of magnetism, it must be explored from the atomic scale combining with experiments and theoretical calculations. |
