Scientists at the University of Tyumen have become the world’s first to create on an industrial scale a number of unique chemical compounds necessary to develop photonic supercomputers and solar batteries on underwater vehicles. The results of their study have been published in the Journal of Alloys and Compounds.
Complex sulphides are substances with semiconductor properties. According to scientists, these substances have been around for several decades, but due to the extremely complex synthesis technology, they were not of practical use.
Researchers at the University of Tyumen have managed to improve the production methods for complex lanthanide sulphides (BaLnCuS3), the most promising group of this type of substances. The scientists have also become the world’s first to obtain BaPrCuS3 and BaSmCuS3 compounds with the new technology.
According to the scientists at the University of Tyumen, the new method is much simpler, quicker, and cheaper than other existing methods, which makes it optimal for industrial production. Due to the complicated synthesis in this type of compounds, according to the scientists, it has been quite hard even to study their crystal structure and basic physical and chemical properties.
According to the University of Tyumen’s researchers, the study has shown that complex sulphide semiconductor elements can be used at extremely high temperatures, up to 1,300°C, for example, in volcanic activity zones or in space under direct exposure of the sun.
Moreover, as the University of Tyumen’s scientists explained, substances of this type absorb green and yellow light from the visible spectrum, which can be used to create solar cells on underwater vehicles. According to the scientists, such devices will be able to receive solar energy at a depth of up to 50 metres.
The study of the obtained compounds was supported by the Kirensky Institute of Physics of SB RAS, the Federal Research Centre Krasnoyarsk Scientific Centre of the Siberian Branch of the RAS, and the Rzhanov Institute of Semiconductor Physics of the Siberian Branch of the RAS. The study also involved experts from the Indian Institute of Technology. In the future, the scientists want to continue studying the new substances’ properties.
