Abstract

We systematically investigated electronic evolutions of nonsymmorphic borophene with chemical environments that were realized by the ion exchange method. Electronic structures can be characterized by the topological invariant. Spectroscopic experiments and DFT calculations unveiled that a sheet of hydrogenated borophene (borophane) is the Dirac nodal loop semimetal ( ), while a layered crystal of YCrB 4 is an insulator ( ). The results demonstrate the electronic topological transition by replacement of the counter atoms on the nonsymmorphic borophene layer.
