Abstract
dc.description.abstract
This work reports a systematic study of the structural and electrical behavior of three ternary
phases of the TaxMo1-xS2 system (x = 0.55, 0.75 and 0.90) and their intercalation compounds
resulting from both chemical and electrochemical lithium insertions, as well as from pyridine and
poly(ethylene oxide) intercalations. The three ternary phases were prepared by direct reaction
of their constituting elements, without any other additive, at 900 ºC in inert atmosphere. The
resulting compounds were characterized by means of X-ray powder diffractometry (XRD),
thermogravimetric and differential thermal (TGA/DTA) analyses, energy dispersive X-ray
fluorescence (EDX) and field emission-scanning electron microscopy (FE-SEM). The electrical
conductivity of the different products was measured in the 1.5-300 K temperature range using the
conventional four probe van der Pauw method in the presence of a 9 T magnetic field in order to
verify the occurrence of magnetoresistivity phenomena
