英文摘要We report systematically studies of de Haas-van Alphen (dHvA) and Shubnikov-de Haas (SdH) quantum oscillations under high magnetic fields on gray arsenic, which has been suggested to be a topological insulator by first-principles calculations and angle-resolved photoemission spectroscopy. We observed large unsaturated magnetoresistance and pronounced quantum oscillations in two methods. By analysis of these quantum oscillation spectra, we obtained two major frequency branches around 3.8-18 and 153-162 T, and the light effective quasiparticle mass and nontrivial Berry phase. These results suggest that bulk crystals of gray arsenic may belong to the category of topological Dirac semimetals rather than topological insulators.
