摘要

在这篇评论中，我们使用作者提供的体积和剪切模量重新计算了Nazir等人研究的双钙钛矿Li2AgSbX6 （X = Cl, Br， I）化合物的维氏硬度值。作者报告说，这些化合物是超硬材料。然而，对论文的仔细审查揭示了硬度计算中的一个重大数值错误，导致了误导性的解释。这些值的校正对于准确解释化合物的力学性能是很重要的。我们重新正确计算的维氏硬度值，将能够更准确地评估化合物的机械性能。

Comment on the paper titled “Study of mechanical, optoelectronic, and thermoelectric aspects of lithium-based double perovskites Li2AgSbX6 (X = Cl, Br, I) for energy harvesting applications” [Mater. Sci. Eng.: B, 309 (2024) 117651]

In this comment, we have recalculated the Vickers hardness values of double perovskites Li₂AgSbX₆ (X = Cl, Br, I) compounds studied by Nazir et al. [1] using the bulk and shear moduli provided by the authors. The authors reported that these compounds are ultra-hard materials. However, a careful review of the paper revealed a significant numerical error in the hardness calculations, resulting in misleading interpretations. The correction of these values is important for the accurate interpretation of the mechanical properties of the compounds. The Vickers hardness values, which we have recalculated correctly, will enable a more accurate assessment of the mechanical properties of the compounds.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
