Synthesis and electrophysical properties of composite materials based on heterostructures CuS/CdS, Cu2S/CdS, Ag2S/CdS

Abstract: Polymer composite materials based on CuS/ CdS, Cu 2 S/CdS and Ag 2 S/CdS were obtained by substitution of Cd with Ag, Cu (II) and Cu (I) ions in the CdS rodlike nanocrystalline and investigated their electrophysical properties. It was found that the electrical conductivity of CuS/CdS heterostructure is in five orders higher compared to the CdS. It was shown that the values of the complex permittivity at identical content of CuS and Cu 2 S nanoparticles are more than 40 % higher for the 0.3 Cu 2 S/CdS-PVDF syst… Show more

“…Identification of the structural characteristics was performed using diffraction patterns. XRD In the presence of the crystal structure of CuS with posistor type conductivity on the surface of ZnS along the entire length of the sample, the temperature dependence of the electrical conductivity of the heterostructure CuS/ZnS should also have a metallic character [8]. For the test samples CuS/ZnS in the temperature dependence of electrical conductivity with increasing amounts of CuS decrease in the angle of inclination of the curves was observed (Fig.…”

“…The observed three main diffraction peaks of ZnS at 2θ = 28.9, 48.1 and 57.1° correspond to (111), (220) and (311) planes. The size of the synthesized ZnS/CdS nanorods is an average length of 150-200 nm and a thickness approximately of 20 nm [13].…”

“…Тому спочатку ми синтезували та вивчили властивості широкого асортименту експериментальних наноматеріалів з магнітними і діелектричними втратами. До них, зокрема, належать матеріали на основі речовин з розвиненою поверхнею і фазовими нестабільностями типу метал-діелектрик, метал-напівпровідник, провідник-надпровідник [17], нанорозмірні ферити та їх тверді розчини [6][7][8][9], багатостінні вуглецеві нанотрубки (БВНТ) та нановолокнисті структури [18,19], графенові нанопластини та їх нанокомпозити [20], метал-вуглецеві нанокомпозити типу ядро-оболонка [21], нанорозмірні напівпровідникові та іонпровідні структури [22][23][24] тощо.…”
