Resume: We present a detailed study of the evolution of the electrical, galvanomagnetic, and thermodynamic properties of polycrystalline AgxMo9Se11 compounds for 3.4 ? x ? 3.8 at low temperatures (2?350 K). In agreement with density functional theory calculations, the collected data show an overall gradual variation in the transport properties from metallic to semiconducting behavior on going from x = 3.4 to 3.8. The results evidence subtle variations in the electronic properties with the Ag content, typified by both positive and negative phonon-drag effects together with thermopower and Hall coefficient of opposite signs. Analysis of the data suggests that these features may be due to peculiarities of the dispersion of the valence bands in the vicinity of the chemical potential. A drastic influence of the Ag content on the thermal transport was evidenced by a pronounced change in the temperature dependence of the specific heat below 10 K. Nonlinearities in the Cp(T3) data are correlated to the concentration of Ag atoms, with an increase in x resulting in a more pronounced departure from a Debye law. The observed behavior mirrors that of ionic conductors, suggesting that AgxMo9Se11 for x ? 3.6 might belong to this class of compounds.

Resume: Abstract In this paper, we report the electrodeposition of stoichiometric Bi2Te3 compound using an ionic liquid binary mixture: 1-ethyl-1-octyl-piperidinium bis(trifluoromethylsulfonyl)imide: 1-ethyl-1-octyl-piperidinium bromide (EOPipTFSI:EOPipBr 95:5 (mol%)). The use of this mixture allows to reach a higher solubility of Bi(III) and Te(IV) precursors compared to pure EOPipTFSI ionic liquid in which Te(IV) salts are not soluble. Moreover, this electrolyte presents an extended cathodic stability, allowing the study of electrochemical processes that occur at high cathodic potential values. A detailed voltammetric study of electrochemical systems was performed for electrolytes containing different [Bi(III)]/[Te(IV)] ratio, allowing the attribution of cathodic signals to electrochemical processes. Experimental conditions leading to the deposition of stoichiometric Bi2Te3 were then determined by varying deposition potential and electrolyte composition, using potentiostatic experiments followed by XRD and SEM-EDX analysis. By varying the concentration of precursors in the electrolyte, mirror-like coatings, adherent and homogeneous, were obtained. Electroplated Bi2Te3 presents n-type conductivity with a Seebeck coefficient equal to ?70 ?V K?1 and an electrical resistivity of 133 ?? m.
