ABSTRACT

ABSTRACT

High-entropy materials (HEMs) are widely recognized for their remarkable resistance to degradation and exceptional mechanical characteristics, rendering them valuable for use in challenging environments. Simultaneously, the investigation of novel attributes of HEMs has long been a crucial focus of scientific exploration. Based on this theoretical framework, we devised and produced a sequence of original bulk Ti_0.2Nb_0.2Ta_0.2Mo_0.2W_0.2C_1-xN_x (0 ≤ x ≤ 0.45) superconductors. Furthermore, it has been observed that Ti_0.2Nb_0.2Ta_0.2Mo_0.2W_0.2C_1-xN_x HECN ceramics possess type-Ⅱ Dirac points in the electronic band structure, implying that these unique bulk HECN ceramics have potential as candidates to bridge superconductivity with topology. These discoveries enhance our comprehension of the physical properties and potential applications of HECN ceramics, thereby establishing them as a promising platform for exploring unconventional physics, such as band topology and superconductivity.
