Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs3 (IMAGE)
Caption
Figure 2: Magneto-infrared spectroscopy and schematic diagram of the electronic structure of CaAs3. a, False-color plot of relative magneto-reflectivity spectra. b, The comparison between effective mass extracted from the quantum oscillations and interband-Landau-level transition. c, Sketch of the band dispersion (left) and DOS (right) in CaAs3. The yellow and light blue regions separated by the mobility edge represent the extended and localized states, respectively, and the orange region corresponds to conducting carriers of the extended states near the Fermi energy EF.
