| contents | In recent years, a type of topological semimetals (TSMs) that can host new fermions with high-fold degeneracy has attracted considerable interest. Among them, ones with chiral structrue particularly catch our attention. Such chiral high-fold degenerate semimetals always have a larger topological charge and longer Fermi arcs which bringing about some special properties. In this work, we found 147 chiral materials with exotic fermions near Fermi level by high-throughput calculation and screening. We selected some typical examples to analyse its topological properties such as topological surface states (TSSs) and Berry curvature. Our results are helpful to provide a promising platform for exploring the physical properties of chiral fermions and application of chiral TSMs. |
