利用神舟3号飞船(SZ-3)上的多样品空间晶体炉制备出GaMnSb材料.所设计的石英安瓿使用氧化铝棉毡和特殊设计制造的氮化硼坩锅进行减震,经受住了严峻的力学环境的考验,完成了材料的空间生长实验,达到了空间生长材料的初步要求.对空间生长的GaMnSb晶体进行了X射线能谱分析和X射线衍射分析,发现空间生长的GaMnSb是多晶结构.对未获得GaMnSb单晶的原因进行了分析,发现空间晶体炉温度的波动和提供能量的不足是导致生成GaMnSb多晶结构的主要原因.由于在晶体生长的初始阶段晶体炉提供的能量不足,使GaSb单晶部分未能熔化,从而导致GaMnSb材料的生长在没有籽晶的情况下进行.
GaMnSb materials were prepared using a multi-sample space crystal furnace on the ShenZhen 3 spacecraft (SZ-3). The designed quartz ampoules were cushioned with alumina cotton felt and a specially designed boron nitride crucible, Of the mechanical environment of the test, the completion of the material space growth experiments, to achieve the initial space-grown material requirements.For the space-grown GaMnSb crystal X-ray energy spectrum analysis and X-ray diffraction analysis found that space-grown GaMnSb is polycrystalline Structure.The reason why GaMnSb single crystal was not obtained was analyzed and it was found that the temperature fluctuation and the lack of energy supply in the space crystal furnace are the main reasons leading to the GaMnSb polycrystalline structure.Due to the lack of energy provided by the crystal furnace in the initial stage of crystal growth , The GaSb single crystal portion was not melted, resulting in the growth of the GaMnSb material without the seed crystal.
