"Borophene", a 2-dimensional layer of boron atoms, holds the electronic properties which researchers try to implement in graphene – and even more.
In the latest issue of Science, Hermann Sachdev, a researcher from Professor Müllen’s department at the Max Planck Institute for Polymer Research (MPI-P) in Mainz, Germany discusses the outlooks of borophene layers. Borophene - now experimentally proven to exist - consists of a two-dimensional layer of boron atoms and has a structure similar to graphene.
It shows electronic properties comparable with those of graphene. Its strongly bound atoms make it resistant to mechanical impact. With remarkable properties, this material will possibly play a key role in future 2D materials research and thin film technology.
In the periodic system, boron is located between metallic beryllium and nonmetallic carbon which classifies it as a semimetal. It displays a pronounced ability to form not only stable electron-deficient bonds, but also strong covalent bonds.
The latter are responsible for boron and borides being among the hardest materials known. The 2D borophene layers can be considered as an intermediate between fully covalently bound graphene and substrate stabilized 2D materials like silicene or germanene. The borophene band structure can be easily tuned by e.g. substrate interactions or surface modifications.
“With these properties, borophene could soon find its way into new applications – ranging for example from electronic sensors and semiconductors to tribological devices”, says Herman Sachdev.
It indeed looks like a very promising material yet its synthesis is currently more complicated than that of graphene and requires further investigation.
Borophene will not become the material of choice to replace graphene in bulk applications like batteries or inks. However it will definitely have its share in the semiconductor device technology and tribology, the science of surfaces interacting in motion.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
