METHOD FOR OBTAINING HETERONANOSTRUCTURES AgS/Ag Russian patent published in 2017 - IPC C01G5/00 B82B3/00 B82Y30/00 B82Y40/00 B82Y5/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in optoelectronics and nanoelectronics as resistance switches and non-volatile memory devices. Method for obtaining heteronanostructures of Ag₂S/Ag involves the preparation of a mixture of aqueous solutions of silver nitrate, sodium sulfide, and sodium citrate, taken in a ratio of 1: 0.1÷1.2 : 0.05÷1.8, aging for 5-100 minutes at a temperature of 20-35°C and radiation irradiation with a wavelength of 460-650 nm and a light flux of 400-6000 lm for 5-100 min. The invention allows to receive a biphasic heteronanostructure of Ag₂S/Ag of the "semiconductor/metal" type with predefined ranges in size from 10 to 80 nm, where semiconductor and metal components are coherently linked.

EFFECT: improved method.
