A new semiconductor material tetrakis-μ3-(methoxy)(methanol)-pentakis(acetylacetonato) (tricopper(II), dysprosium(III)) (I) was synthesized, with the following composition: [Cu3Dy(AA)5(OCH3)4CH3OH], where HAA = H3C–C(O)–CH2–C(O)–CH3. By data of the elemental analysis and physic-chemical research methods, the obtained complex compound (I) was established to contain atoms of copper (II) and dysprosium (III) in a ratio Cu : Dy = 3 : 1, and its composition was established to correspond to a gross formula: Cu3DyО15C30Н51. The electrical conductivity of the obtained material was measured in compressed form. The following parameters were calculated for the complex compound (I): the number of valence electrons in one molecule was 276; the mass of one molecule was 166.777∙10-20 kg; the total number of molecules in a cylindrical sample with a 0.138 g mass and a 19.72∙10-9 m3 volume was 8.274∙1013 molecules. The resistivity of the pressed sample decreases from 9∙1010 to 7∙104 Ohm∙cm in a 303 ~ 413 K temperature range. This confirms that the synthesized compound is a semiconductor with a bandgap of 1.38 eV. The conductive properties of the complex compound as a heat-sensitive element were studied. An experimental sample of compressed material with geometric sizes of 1·10-3m×0.5·10-3m×0.5·10-3m was employed for investigations. |
