Abstract Transition metal dichalcogenides (TMDs), exhibit a range of crystal structures and topological quantum states. The 1T phase, in particular, shows promise for superconductivity driven by electron-phonon coupling (EPC), strain, pressure, and chemical doping. In this theoretical investigation, we explore 1T-RhSeTe as a novel type of TMD superconductor with topological electronic states. The optimal doping structure and atomic arrangement of 1T-RhSeTe are constructed. Phonon spectrum calculations validate the integrity of the constructed doping structure. The analysis of the electron-phonon coupling using the electron-phonon Wannier (EPW) method has confirmed the existence of a robust electron-phonon interaction in 1T-RhSeTe, resulting in total EPC constant λ = 2.02, the logarithmic average frequency ωlog = 3.15 meV and Tc = 4.61 K, consistent with experimental measurements and indicative of its classification as a BCS superconductor. The band structure analysis revealed the presence of Dirac-like band crossing points. The topological non-trivial electronic structures of the 1T-RhSeTe are confirmed via the evolution of Wannier charge centers (WCCs) and time-reversal symmetry-protected topological surface states (TSSs). These distinctive properties underscore 1T-RhSeTe as a possible candidate for a topological superconductor, warranting further investigation into its potential implications and applications.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
