Retrahedrons O-Al4 and O-Fe4 exist in the Shandong sapphire, while other Tetrahedrons such as O-Al3Fe, O-Al2Fe2 and O-AlFe3 may also exist.

研究表明，山东蓝宝石中Fe主要是以Fe~(3+)的形式存在的；Fe含量的周期性变化主要表现为Fe~(3+)含量的周期性变化；而在蓝宝石中，Fe主要是以类质同象的形式替换Al而进入刚玉晶格的，在刚玉晶格中存在着O-Al_4，和O-Fe_4的结构格式，也极有可能存在着二者的几个过渡型分子结构如O-Al_3Fe，O-Al_2Fe_2及O-AlFe_3。

Firstly, the incommensurate magnetic scattering of the doped single-layer triangular lattice in the normal state has been studied. It is shown that away from half-filling the commensurate peak is replaced by six incommensurate peaks located at [ (1-δ〓), ] , [ (1-δ′〓), ] , [ (1-δ"〓), ] , respectively, and 〓〓. The incommensurability parameter δ increases with doping at lower doping concentration, while saturates at higher dopings. These peaks broaden and weaken in amplitude with increasing energy and temperature, with the positions of the incommensurate peaks not changing with the energy.

利用t-J模型，讨论了单层和双层三角晶格材料的非公度磁散射，结果表明：随着掺杂的增加，三角晶格反铁磁体出现公度-非公度转变，即由一个公度峰变为六个非公度峰，并且非公度率在较低掺杂时随着掺杂浓度的增大而增大，在较高掺杂浓度时将达到饱和；虽然非公度峰的权重随着能量的增大而减小，但非公度峰的位置与能量无关，即非公度率是不随能量变化的，并且我们还发现非公度峰的权重随着温度的升高也是减小的。

However, it will be reduced by the effect of phonons scattering, which is caused by point defects and crystal boundaries.

这一结果可解释为：常温下半导体材料的热导率主要是由晶格热导率决定，晶格热导率的大小由导热声子的输运过程决定的。

Raman spectra indicate a lower density of phonons of nano-samples than that of a bulk one.

在Raman谱上观察到的散射峰强度随颗粒度减小而下降，即声子密度下降的效应，也可以归功于表面态和界面态上未能形成完善的晶胞，晶格振动的格波难以形成。
