Summary: Porous carbon materials are investigated as an electrode component of supercapacitors (SC). The materials are obtained from vegetable organic raw materials by using a technique of pyrolysis with a subsequent activation in a potassium hydroxide solution. We have found an effect of which is similar to that of inductance in a. c. circuits.
Keywords: supercapacitor, plant material, inductance, electrode.
Summary: Heterostructure p-GaTe–n-InSe was prepared by the method of mechanical contact of GaTe oxidized plate with van der Waals surface of InSe. Topology of surfaces of GaTe and InSe layered crystals were studied by using AFM-images. It is shown that there was formed thin oxide dielectric layer of Ga2O3 on the heterojunction p-GaTe–n-InSe.The direct branch ofthe current-voltage characteristics of the heterostructure show high diode properties. Sensitivity spectral area of p‑GaTe – n-InSe heterostructure was identified and the characteristics of its energy band diagram were shown.
Key words: indium selenide, layered crystals, heterojunction, AFM-images spectral characteristics.
