  Platinum-group transition-metal dichalcogenides have emerged as a subject of
considerable interest in condensed matter physics due to their remarkable
topological properties and unconventional superconducting behavior. In this
study, we report the synthesis and superconducting characteristics of a new
Dirac-type topological semimetallic compound 1$T$-RhSeTe. It shows type-II
superconductivity with a superconducting transition temperature of 4.72 K and a
high upper critical field. The coexistence of superconductivity and topological
properties makes it a prime candidate for hosting topological
superconductivity.
