A group of physicists from Moscow State University (MSU Lomonosov) under the guidance of Professor Alexander N. Obraztsov, who worked with the support of Russian scientific Foundation, found a way to obtain diamond crystallites suitable for industry forms, and also studied their properties of the luminescence. Crystals with such properties can help the development of the domestic industry in the production of cutting tools, sensors, quantum-optical devices, quantum computers, probes for scanning microscopes, and so on.

According to Alexander N., although this work refers to research studies which do not involve specific industrial and technological applications, “the preliminary results showed a high potential application and has been partially commercialized. There are devices available in the market, which are made with a help of our studies.” In particular, AFM cantilevers with single crystal diamond needle of the company TipsNano.

Diamonds are used in industry in greater volume than diamonds for jewelry pf beautiful ladies. This also requires grinding processing to obtain the desired properties. The practical applicability of the method is determined by its cost, and our scientists have proposed a method of using diamond films obtained from crystallites elongated shape, by heating it at a certain temperature. This method enables to control the shape, size and properties of the obtained crystallites, ensuring their effective application in industry.

The study represents only one of a number of high-tech tasks of our physicists. As told Alexander to “E-Vesti”: “In our Laboratory, Carbon Materials Department of physics of polymers and crystals of Moscow state University physical Department, we are engaged in scientific research on various aspects related to obtaining, studying of properties and development of scientific principles of applications of carbon materials of various types including diamond, graphene, carbon nanotubes, nanostructured graphite, etc”.
