In this work, we present a study of new Kagome superconductor metal discovered for the first time into Half-Heusler NbRhSb. We followed a method based on density functional theory (DFT) combined with another method based on weak binding called Tight-Binding to determine its topological indices. This method is very efficient and widely used in ab initio studies to extract Chern number “C” and the topological number “Z2”. The application of SOC generates an opening between the bands equal to 160 meV due to the point of contact between flat bands and the Dirac cone. The results show that NbRhSb has a nonzero number topological with cone Dirac and flat bands near Fermi level. All indices indicate that NbRhSb intermetallic has the possibility to be non-trivial superconductivity.
