This work investigates the vibrational and electrical properties of molybdenum trioxide (α-MoO₃) upon tensile strain applied along different crystal directions. Using a three-point bending setup in combination with Raman spectroscopy, we report measurements of a blueshift of the Raman modes when uniaxial tensile strain is applied along the a- and c-axis to this material. Furthermore, the electrical measurements reveal an increase in resistance with strain applied along both in-plane directions. The findings from the uniaxial strain and Raman spectroscopy measurements are further confirmed by ab-initio calculations. This study provides valuable insights into the mechanical and vibrational properties of α-MoO₃ and its potential use in several applications. This study contributes to the growing body of knowledge on the properties of α-MoO₃ and lays the foundation for further exploration of its potential applications. Given MoO₃ holding the natural hyperbolic phonon polaritons, attracting significant research interest, this study has the potential to arouse the curiosity of the scientific community.

这项工作研究了沿不同晶体方向施加拉伸应变时三氧化钼 (α-MoO ₃ )的振动和电学特性。使用三点弯曲设置与拉曼光谱相结合，我们报告了当沿 a轴和c轴向该材料施加单轴拉伸应变时拉曼模式蓝移的测量结果。此外，电气测量结果表明，随着沿两个面内方向施加的应变，电阻会增加。单轴应变和拉曼光谱测量的结果通过从头计算得到进一步证实。_{这项研究为 α-MoO 3}的机械和振动特性及其在多种应用中的潜在用途提供了宝贵的见解。这项研究有助于不断丰富关于α-MoO ₃性质的知识，并为进一步探索其潜在应用奠定基础。鉴于MoO ₃拥有天然的双曲声子极化激元，吸引了人们极大的研究兴趣，这项研究有可能引起科学界的好奇。
