Abstract

The Shubnikov-deHaas (SdH) effect has been used to study the electronic properties of graphit intercalated with PdCl2 (stage 3), FeCl3 (stages 2, 4, 6, and 11), CuCl2 (stage 1), and WCl6 (stage 5). For the palladium chloride, ferric chloride, and copper chloride intercalants the SdH spectra are similar: these show frequencies of approximately, 27, 80, 380, and 550 Tesla for fields parallel to the c-axis. The effective masses have been measured for each of these carriers, and are of the order of 0.1 mo, where mo is the free electron mass. These carriers have mobilities of the order of 104 cm2/V s at 4 Kelvin. No graphite frequencies (4.7 and 6.3 Tesla) were observed. The similarity of data for these compounds suggests comparable charge transfer and Fermi surfaces. Data from the tungsten chloride compound are somewhat different: the majority carrier electron frequency for pure graphite was observed, as well as frequencies of 76 and 540 Tesla. Air stability of all compounds was studied. In addition, we have used differential thermal analysis, X-ray diffraction, and scanning and transmission electron microscopy to characterize the material.
