Found replacing graphene - semiconductor is one atom thick

Semiconductors thickness of only one atom - is no longer science fiction, but a reality, though not yet embodied in certain devices. Physicists from the University of Bayreuth (Germany), Dr. Axel Enders (Axel Enders) in collaboration with scientists from Poland and the United States replacing graphene has been developed - a two-dimensional material that can bring electronics to the next level. Due to its semiconductor qualities, this material may be more suitable for use in electronics than graphene.

Found replacing graphene - semiconductor is one atom thick

It should be recalled that graphene was developed in 2004 and is considered an important step taken by science. The new material, in addition to carbon, also contains boron and nitrogen. Its chemical name - "Hexagonal boron-carbon-nitrogen" ( "Hexagonal Boron-Carbon-Nitrogen", h-BCN). The results of this important high-technology research published scientific publication ACS Nano.

Professor Anders believes that the results of them, together with other scientists research can be a starting point for a new generation of electronic transistors, circuits and sensors that will be much smaller and more flexible than those elements, which are used in electronics today. It is also likely to be achieved and a significant reduction in power consumption.

Professor Enders notes that now dominates the electronics industry CMOS-technology is characterized by explicit restrictions that prevent its further miniaturization. The researchers noted that the h-BCN is more appropriate to address these material limitations than graphene. It should be recalled that graphene - two-dimensional "lattice", is entirely composed of graphene atoms. Its thickness - only one atom. Once scientists began to study more carefully the structure of their remarkable properties enthused worldwide. Indeed, graphene is stronger than steel at 100-300. At the same time it is an excellent conductor of heat and electricity. The electrons are free to go at any applied voltage through it, because it does not provide any specific provisions of the "on" and "off".

For this reason, says Professor Anders, graphene is not sufficiently suitable for most electronic devices. Because of semiconductors are required to be provided to switch between the "on" and "off". So the scientist had the idea to replace some of the graphene carbon atoms of boron and nitrogen. The result of this project was a two-dimensional "lattice", having the properties of the semiconductor. In the embodiment of this idea he helped a team of scientists from the University of Nebraska-Lincoln. Research was carried out in partnership with scientists from Krakow University, State University of New York, Boston College and Tufts University.
