Electronics to a new level displays a two-dimensional material. And that's not graphene

Since the discovery of graphene (a material with two-dimensional structure, which is based on carbon) in 2004, scientists speculated about the presence of other materials with similar properties. Theorists had predicted that boron can form a two-dimensional material like graphene. But experimentally it was confirmed only three years ago. Then the scientists first synthesized Borovan. And now a group of experts from the US have developed a new technology that could give impetus to the development of a new kind of electronics.

Borovan — is a two dimensional material, presented in the form of thin sheets with a thickness of one atom. Sounds pretty ordinary, if not its properties. The fact that in the usual form, the boron atom — is a non-metallic semiconductor, but a two-dimensional form is already becoming a metallic conductor.

"Baropen structurally similar to graphene and has a hexagonal network of boron atoms on each of the six vertices. However Borovan is characterized in that it periodically has an additional boron atom in the center of the hexagon. The crystal structure tends to be stable when approximately four out of every five Central positions are busy and one is free. While jobs are distributed in such a way as to maintain the most stable structure, they can be rebuilt. Because of this flexibility boroden can have multiple configurations." — said Ivan Bozovic, senior researcher at Brookhaven National Laboratory.

Scientists from the Brookhaven National Laboratory and Yale University studied the growth of borovina on the silver surface. In the course of a series of transformations they did "too little" morafenobe crystals that are impossible to apply in practice. Then the experts changed the silver on the copper substrate. The resulting crystals were larger and they can be used.

"In today's chips use single crystals of silicon and other semiconductors. Thanks to Borodino you can increase the size of single crystal domains in a million times. This will allow to create electronic devices of new generation with high performance."

The Growth of borovina you can see on the video, available below.
