Abstract: Disclosed is a high-resistance resistor based on silicon carbide. The resistor includes a semi-insulating 4H—SiC silicon carbide substrate, a silicon surface and a carbon surface of the silicon carbide substrate are provided with symmetrical atomic-thickness aluminum oxide insulating layers, thicknesses of the aluminum oxide insulating layers are 0.2 nm-2 nm, conductive metal electrodes are formed at two sides of the aluminum oxide insulating layers through evaporation, and thicknesses of the metal electrodes are 100 nm-500 nm. The present disclosure uses a high-resistance resistor based on silicon carbide that has the above structure, makes an ohmic contact electrode on a semi-insulating silicon carbide substrate, thus obtaining a resistor with a resistance of 100 TΩ or more, and satisfying requirements of the precision measurement industry.

Abstract: This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color. The electroluminescent spectrum of the conjugated polymer in the present application covers the whole visible light emission area and is close to the pure white light emission, by which the conjugated polymer could be used as a material used in light-emitting layer to prepare the organic electroluminescent devices.
