Stacking Structure

Intercalate interlayer stacking structures in stage-1 graphite intercalation compounds of type MC6 are studied within the framework of the mean-field lattice gas model. On the basis of the result obtained, the observed difference of the stacking sequences between LiC6 and otherMC6 compounds, M = Sr, Ba, Eu, and Yb, is discussed. In the latter cases, comment is made on the possibility of having order–order transitions associated with changes in the stacking sequences at low temperatures.

AbstractIntercalation compounds of graphite with Sn(CH3)3Cl have been prepared by UV irradiation, in the presence of graphite, of solutions of Sn(CH3)3Cl, Sn(CH3)4, or of Sn(CH3)4 + SnCl4 in CCl4. Mixtures of stage 1, stage 2, and stage 3 compounds have been obtained. They were characterized by X-ray diffraction, 119Sn Mossbauer spectroscopy, and by chemical analysis. Apparently an oligomeric, anionic species is intercalated together with some solvent.

ABSTRACTStudy of the microstructure of electronic materials can be enhanced by using high resolution transmission electron microscopy (TEM) combined with the technique of digitized image analysis. We show here a practical image analysis method for the microstructures of acceptor graphite intercalation compounds (GICs) with CuCl2 and FeCl3 intercalates. The two dimensional fast Fourier transform (2D-FFT) was used for the frequency analysis of the TEM pictures. It is found that the lattice images of CuCl2-GICs consist of different frequency images corresponding to specific frequencies. The detailed features of the stage-1 structure of the FeCl3-GICs is extracted quantitatively by this method from a relatively indistinct TEM picture. The stage structure of the CuCl2- and FeCl3-GICs are further investigated by analyzing the reconstruction of the TEM images by means of the two dimensional inverse FFT (2D-IFFT).

AbstractScanning tunneling microscopy (STM) is used to visualize the structure of copper chloride and cobalt chloride graphite intercalation compounds (GICs). When the samples are biased negatively with respect to the tip, the images show details of the structure of the intercalant layers, and of its effects on the surface graphene layer. When the sample is under positive bias, symmetry properties of the uppermost graphite planes are revealed. Images of the CuCl2 stage 1 GIC display a hexagonal symmetry in which all the atoms of the graphite surface plane appear. This is in contrast to the three-fold symmetry usually seen in atomic resolution STM images of highly oriented pyrolytic graphite (HOPG), which we also observe on a reference sample of HOPG. The three-fold symmetry is attributed to the ABAB stacking of the atomic layers in HOPG. In GICs, this stacking sequence is interrupted by the layer of intercalate, so that for the stage 1 compound all carbon atoms in the plane become equivalent, and six-fold symmetry develops. For a stage 2 (CuC12 or CoCl2) GIC three-fold symmetry is expected to persist. Images of the CoCl2 stage 1 GIC, taken with the sample bias is positive with respect to the tip, display a mixed trigonal and hexagonal symmetry, and may be attributable to the fact that the surface of sample is of mixed stage.
