2023年12月10日 · The XRD pattern for the (Y 0.2 Dy 0.2 Ho 0.2 Tb 0.2 Lu 0.2) (Cr 0.2 Mo 0.2 W 0.2 Re 0.2 Ru 0.2)B 4 HEB is shown in Fig. 2 (b). One can see that all the diffraction peaks can be well indexed on the orthorhombic YCrB 4-type structure with the Pbam space group. Nevertheless, the residual stress cannot be determined by the XRD method since the ...

The following shows the X-ray diffraction (XRD)[Source-code] pattern and the Radial distribution function (RDF) plots [Source-code]. XRD peaks should be comparable to experiments for bulk structures. Relative intensities may differ.

2023年11月1日 · YCrB 4 is a promising semiconductor material with good thermoelectric properties and a good power factor of 6.0 µW cm −1 K −2 at 500 K (Simonson & Poon, 2010 #; Flipo et al., 2021 #). The YCrB 4 compound is also expected to be a super-hard material (Akopov et al., 2018 #) and a narrow bandgap semiconductor (Medvedeva et al., 2002 #).

YCrB4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Y3+ is bonded in a 4-coordinate geometry to fourteen B+1.50- atoms. There are a spread of Y–B bond distances ranging from 2.61–2.74 Å. Cr3+ is bonded in a 11-coordinate geometry to one Cr3+ and ten B+1.50- atoms. The Cr–Cr bond length is 2.32 Å.

基于单晶x射线衍射数据精修了四硼化钇铬ycrb4的结构参数。 YCrB4 是斜方晶系，具有 Pbam 型空间群（编号 55），晶格参数为 a = 5.9425 (2)、b = 11.4831 (4)、c = 3.4643 (1) Å。

2023年10月26日 · The structural parameters of yttrium chromium tetra-boride YCrB 4 were refined based on single-crystal X-ray diffraction data. YCrB 4 is ortho-rhom-bic, having a space group of type Pbam (No. 55) and with lattice parameters of a …

2023年12月1日 · Through discussing the thermodynamics process related to these possible chemical reactions and combining the XRD results at different temperatures, it was obtained that higher temperature and ...

In this study, the physical such as structural, electronic, anisotropic elastic and lattice dynamic properties of YXB4 (X = Cr, Mn, Fe and Co) compounds have been investigated. The electronic...

2023年11月11日 · YCrB 4 is a promising semiconductor material with good thermoelectric properties and a good power factor of 6.0 µW cm −1 K −2 at 500 K (Simonson & Poon, 2010 ; Flipo et al., 2021 ). The YCrB 4 compound is also expected to be a super-hard material (Akopov et al., 2018 ) and a narrow bandgap semiconductor (Medvedeva et al., 2002 ).

2023年3月27日 · Figure 4 shows a collection of X-ray diffraction (XRD) patterns of the HB and YCrB 4 samples. Diffraction peaks of the YCrB 4 crystals were found at angles, as expected. One can also capture the differences in the XRD signals of YCrB 4 before and after ball milling.
