Transition-metal chalcogenides are prospective thermoelectric materials. One of them is a molybdenum disulfide MoS<sub>2</sub>, which has a layered structure. MoS<sub>2</sub> has a good potential to have a high value of thermoelectric quality factor due to a high value of thermo-EMF and low value of thermal conductivity. But a low value of its electrical(More)

Possible application of tungsten dichalcogenides as gas-sensing elements is discussed in this paper. The experimental results on sensitivity of pristine and niobium doped WS2 and WSe2 to acetone and ethanol gases are presented. Polycrystalline powder specimens were obtained by high temperature solid-state synthesis from the stoichiometric mixture of pure(More)
Transition metal chalcogenides are perspective thermoelectric materials which have a great interest for application. In this work, the polycrystalline bulk WS<sub>2</sub> and solid solutions WS<sub>2-y</sub>Se<sub>y</sub> types have been studied. In contrast to the literature data obtained at higher temperatures, we have investigated the thermoelectric(More)
The paper reports the results of an experimental investigation of electron transport properties and piezoresistive effect of polycrystalline film and bulk samples of tungsten-rhenium disulphide W<sub>0.95</sub>Re<sub>0.05</sub>S<sub>2</sub>. Polycrystalline powder of the composition was synthesized by direct high temperature reaction of elements with(More)
The paper reports experimental study of piezoresistive effect in composite films based on polybenzimidazole with few-layered graphene nanoparticles filler. Colloidal dispersions of few-layered graphene (FLG) were obtained by ultrasonic treatment of synthesized FLG in the solution of poly[2,2′-(p-oxydiphenylen)-5,52′-bisbenzimidazole] (OPBI) in(More)
The work presents a study of piezoresistive effect of thin films of rhenium-doped molybdenum disulfide of composition Mo<sub>0.95</sub>Re<sub>0.05</sub>S<sub>2</sub> possessing layered structure of 2H-MoS<sub>2</sub> type. The compound was synthesized by high temperature ampoule method using stoichiometric mixture of elements. The thin films were formed by(More)
