Electrical Conductivity of Cesium-Graphite Intercalation Compounds during Ternarization by Ethylene and Acetylene

Effect of sorbed molecules on the resistivity of alkali metal–graphite intercalation compounds

“…The sorption-desorption cycle is reversible for H 2 , N 2 , CH 4 , Ar, C 2 H 6 , etc., whereas it is irreversible for tetrahydrofuran (THF), C 2 H 2 , etc. [2,3]. Such difference may be originated from different ways of interaction between molecules and AM-GICs.…”

Thermoelectric Properties of Cesium–Graphite Intercalation Compounds

“…5-this is a typical feature of GICs [22][23][24] -while Grafoil has a semiconductive dependence. 14,25,26) The relatively low electrical conductivities of Cs-benzene-GIC and Cs-acrylonitril-GIC shown in Table 1 were attributed to their lower air stability, because the electrical conductivity of a sample is strongly affected by its decomposition in air. 10,21) The thermal conductivities of the Cs-GICs were 50-100 Wm À1 K À1 , about 1/4-1/2 of that of Grafoil.…”

“…[9][10][11][12] It has been found that the electrical conductivities of these ternary GICs are somewhat lower than those of their original binary GICs because of the partial electron back-donation from the graphite planes to the Cs atoms. [13][14][15] For the purpose of comparison, K-ethylene-GIC, 16) K-benzene-GIC 17,18) and FeCl 3 -GIC 19,20) were prepared and studied in a similar manner.…”
