摘要：The unique properties of topological metal/ semimetals (TMs) have strongly driven efforts

to seek for new topological phases and related materials. In contrast to the topological materials based on heavy elements, we proposed some topological materials consisting of carbon or boron atoms. The light-element materials exhibit rich topological phases, such as nodal lines/rings,Weyl points, triple points, nexus points, nodal networks, nodal surfaces. In these structures, the topological properties can be clearly clarified by orbital physics. In addition, we also identify that various topological phases can also be obtained by stacking layered two-dimensionalnanosheets. For example, three types of intersecting nodal rings are found in the layered semiconductors.
