A revolutionary atom-thin semiconductor for electronics

We found an article titled ‘A revolutionary atom-thin semiconductor for electronics‘ on phys.org that we thought would be good to share with you.

A two-dimensional material developed by Bayreuth physicist Prof. Dr. Axel Enders together with international partners could revolutionize electronics.

Atom-thin semiconductors are no longer the stuff of science fiction, rather a reality now developed by Bayreuth physicist Prof. Dr. Axel Enders, together with partners in Poland and the US. This two-dimensional material could revolutionise electronics. Due to its semiconductor properties, this material is far better suited for high tech applications than graphene. The discovery of its semiconductor properties versus graphene was celebrated worldwide as a scientific breakthrough in 2004. This new material contains carbon, boron, and nitrogen, and its chemical name is “Hexagonal Boron-Carbon-Nitrogen (h-BCN)”. The new development was published in the journal ACS Nano.

“Our findings could be the starting point for a new generation of electronic transistors, circuits, and sensors that are much smaller and more bendable than the electronic elements used to date. They are likely to enable a considerable decrease in power consumption,” Prof. Enders predicts, citing the CMOS technology that currently dominates the electronics industry. This technology has clear limits with regard to further miniaturisation. “h-BCN is much better suited than graphene when it comes to pushing these limits,” according to Enders.

Graphene is as thin as a single atom, a two-dimensional lattice made up entirely of carbon atoms. As the scientists began to investigate these structures, their remarkable properties were welcomed with enthusiasm across the world. Graphene is 100-300 stronger than steel, at the same time, an excellent conductor of heat and electricity.

However, electrons are able to flow through unhindered at any applied voltage such that there is no defined on-position or off-position. “For this reason, graphene is not well suited for most electronic devices. Semiconductors are required, since only they can ensure switchable on and off states,” Prof. Enders explained. He had the idea of replacing individual carbon atoms in graphene with boron and nitrogen, resulting in a two-dimensional grid with the properties of a semiconductor. He has now been able to turn this idea into reality with his team of scientists at the University of Nebraska-Lincoln.
