Electronics to the next level will bring dimensional material. And this is not the graphene
Since the discovery of graphene (a material with a two-dimensional structure, which is the basis of carbon) in 2004, scientists put forward the hypothesis of the presence of other materials with similar properties. Theorists had predicted that boron can form a two-dimensional material like graphene. But it is experimentally confirmed only three years ago. Then the scientists first synthesized borofen. And now a group of experts from the United States developed a new technology that may well give an impetus to the development of a new type of electronics.
Borofen - dimensional material is presented in the form of thin sheets one atom thick. It sounds quite ordinary, if not for its properties. The fact is that in the usual form of boron atom - is a non-metallic semiconductor, but the two-dimensional shape is already becoming a metallic conductor.
"Borofen structurally similar to graphene, and has a hexagonal network of boron atoms on each of the six vertices. However borofen characterized in that it has a second periodically boron atom in the center of the hexagon. The crystal structure tends to be stable when occupied approximately four and one out of every five free central position. While vacancies are distributed in such a way as to maintain the most stable structure, they can be rebuilt. Because of this flexibility borofen may have several configurations. "- said Ivan Bozovich, a senior fellow at Brookhaven National Laboratory.
Scientists at Brookhaven National Laboratory and Yale University have studied the growth borofena on the silver surface. During a series of transformations they get "too small" borofenovye crystals, which can not be put into practice. Then the experts changed their silver in the copper substrate. The resultant crystals were larger, and they can already be used.
"Modern chips used single crystals of silicon and other semiconductors. Due borofenu can increase the size of the single-crystal domains in a million times. This will create a new generation of electronic devices with high performance. "
