| 英文摘要 | The prediction of topological states in rare-earth monopnictide compounds has attracted renewed interest. Extreme magnetoresistance (XMR) has also been observed in several nonmagnetic rare-earth monopnictide compounds. The origin of XMR in these compounds could be attributed to several mechanisms, such as topologically nontrivial electronic structures and electron-hole carrier balance. YBi is a typical rare-earth monopnictide exhibiting XMR and is expected to have a nontrivial electronic structure. In this work, we perform a direct investigation of the electronic structure of YBi by combining angle-resolved photoemission spectroscopy and theoretical calculations. Our results show that YBi is topologically trivial without the expected band inversion, and they rule out the topological effect as the cause of XMR in YBi. Furthermore, we directly observed nearly perfect electron-hole compensation in the electronic structure of YBi, which could be the primary mechanism accounting for the XMR. |
