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

这些新的分层III-VI稀磁半导体（DMS）系统补充了II-VI DMS中的巨大进展和Mn掺杂的III-V DMS系统中的更近期的努力。III-VI DMS Ga 1-xMnxSe在1.804 eV处表现出归因于Mn的强红光发射。GaSe本身以其显著的非线性光学性质而闻名，是一种有前途的光电应用材料。Ga_（1-x）Mn_xS和In_（1-x）Mn_xS将被详细研究，随后将研究Ga_（1-x）Mn_xSe和In_（1-x）Mn_xSe，并对基于Fe和Co的材料进行调查。初步的非线性磁化标度分析表明，Ga 1-xMnxS在11 K下存在真正的自旋玻璃转变。这一重要结果将增加一个全新的自旋玻璃材料类别，并提出空间维度对该系统中自旋玻璃转变的影响的有趣问题。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（目前在物理学中代表性不足的群体）。这个项目也使这个本科院校的荣誉共享国家的最先进的SQUID磁强计与研究小组在两个研究生和一个本科院校。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中取得的巨大进展。 III-VI DMS Ga 1-xMnxSe表现出归因于Mn的强红光发射。 GaSe本身以其显著的非线性光学性质而闻名，是一种有前途的光电应用材料。 几个III-VI DMS将进行调查，以进一步探索这类最新的DMS的层状III-VI半导体主机的基础上的磁性能。 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（目前在物理学中代表性不足的群体）。 这个项目也使这个本科机构的荣誉分享国家的最先进的SQUID磁强计与研究小组在两个研究生和一个本科院校。

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.
