RUI: Exploration the New Class of Layered III-VI Diluted Magnetic Semiconductors and Their Magnetic Properties

这些新的层状III-VI稀磁半导体(DMS)系统补充了II-VI稀磁半导体(DMS)的巨大进步，以及在掺锰III-V DMS系统方面的最新努力。III-VI型DMS Ga1-xMnxSe在1.804 eV处表现出较强的红光发射，这归因于Mn。GaS本身以其显著的非线性光学性质而闻名，是一种很有前途的光电子应用材料。对Ga1-xMnxS和In1-xMnxS进行了详细的研究，然后对Ga1-xMnxSe、In1-xMnxSe进行了研究，并对Fe和Co基材料进行了综述。对Ga1-xMnxS的初步非线性磁化标度分析表明，在11K时存在真正的自旋玻璃转变，这一重要结果将增加一类全新的自旋玻璃材料，并提出空间维度对该体系自旋玻璃转变的影响这一有趣的问题。就更广泛的影响而言，该项目每年涉及指导3名本科生。该研究小组目前包括1名女性和1名西班牙裔学生(目前在物理学领域代表性不足的群体)。该项目还使这个本科生机构有幸与两个研究生和一个本科生机构的研究小组共享一台最先进的SQUID磁强计。非技术摘要这些新的分层III-VI稀磁半导体(DMS)系统补充了基于其他半导体主机的系统所取得的巨大进步。III-VI型DMS GA1-xMnxSe表现出由Mn引起的强红光发射。GaS本身以其显著的非线性光学性质而闻名，是一种很有前途的光电子应用材料。将对几种III-VI DMS进行研究，以进一步探索基于层状III-VI半导体宿主的这类最新DMS的磁性。就更广泛的影响而言，该项目每年涉及指导3名本科生。该研究小组目前包括一名女性和一名西班牙裔学生(目前在物理学领域代表性不足的群体)。该项目还允许这个本科院校与两个研究生和一个本科生机构的研究小组共享一台最先进的SQUID磁强计。

These new layered III-VI Diluted Magnetic Semiconductor (DMS)systems complement the enormous progress in the II-VI DMS and the more recent efforts in the Mn doped III-V DMS systems. The III-VI DMS Ga1-xMnxSe exhibits a strong red emission at 1.804 eV attributed to the Mn. GaSe itself is known for its remarkable nonlinear optical properties and is a promising material for photoelectronic applications. Ga1-xMnxS and In1-xMnxS will be investigated in detail followed by a study of Ga1-xMnxSe, In1-xMnxSe and a survey of Fe and Co based materials. Preliminary non-linear magnetization scaling analysis on Ga1-xMnxS strongly suggests there is a true spin-glass transition at 11 K. This important result would add a whole new class of spin-glass materials and raise interesting questions of the effect of spatial dimensionality on the spin-glass transition in this system. In terms of broader impacts, this project involves mentoring 3 undergraduate students each year. The research group currently includes 1 female and 1 Hispanic student (currently underrepresented groups in physics). This project also allows this undergraduate institution the honor of sharing a state-of-the-art SQUID magnetometer with research groups at two graduate and one undergraduate institutions.Non-Technical AbstractThese new layered III-VI Diluted Magnetic Semiconductor (DMS) systems complement the enormous progress made in systems based on other semiconductor hosts. The III-VI DMS Ga1-xMnxSe exhibits a strong red emission attributed to the Mn. GaSe itself is known for its remarkable nonlinear optical properties and is a promising material for photoelectronic applications. Several III-VI DMS will be investigated to further explore the magnetic properties of this newest class of DMS based on the layeredIII-VI semiconductor hosts.
