This paper presents a comparative study of the elastic, mechanical, electronic, and optical response of RuCrX (X=Si, Ge, Sn). The materials are found to be flexible and ductile, with high hardness and stiffness, making them suitable for high-temperature environments. They exhibit non-magnetic metallic properties and can be used in opto-electronic devices and sensors.
This paper contains the comparative study of elastic, mechanical, electronic and optical response of RuCrX (X=Si, Ge, Sn). Three independent second order elastic constants are computed and elasto-mechanical stability is checked. Mechanical parameters depicts the flexible and ductile nature. These materials are hard and stiffer, difficult to compress and have an excellent bond stretching minimization phenomenon. The higher melting temperatures make them candidate for the high temperature environment like aerospace and construction industries. The band gap and density of states study reveal the non-magnetic metallic nature of all these alloys. In addition, the Fermi surfaces are also calculated. The imaginary part of dielectric response function confirms the utility in opto-electronic devices and sensors.
