3. About the company
SmS tenzotherm Rus – is a Russian-Germany company that conducts research
and development of products based on a semiconductor material – samarium sulphide.
In 2013 got into 20 most promising start-up companies in Russia under the version of Skolkovo
(Russian analogue of Silicon Valley)
History of the project
1964 – Department of rare-earth semiconductors in Ioffe Physical-Technical Institute
(St. Petersburg, Russia) started the research on samarium sulphide material
2000 – Discovered the thermovoltaic effect
2012 – Attracted venture investments
2012 – Got a status of the project participant in Skolkovo Fund
2013 – Obtained a grant of Skolkovo Fund
2013 – Manufacturing line was launched in Dortmund, Germany

7. The method provides an opportunity to obtain
a substance of known composition and
crystals.
Synthesis of samarium sulphide is a complex
process of capsulation, which in our
laboratory we have developed to perfection.
Synthesis Sm + S = SmS
