Hexagonal boron nitride tagged posts

Rutgers University–New Brunswick researchers have discovered a new class of materials—called intercrystals—with unique electronic properties that could power future technologies.

Intercrystals exhibit newly discovered forms of electronic properties that could pave the way for advancements in more efficient electronic components, quantum computing and environmentally friendly materials, the scientists said.

As described in a report in the science journal Nature Materials, the scientists stacked two ultrathin layers of graphene, each a one-atom-thick sheet of carbon atoms arranged in a hexagonal grid...

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery’s lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night...

Efficient method for making single-atom-thick, wafer-scale materials opens up opportunities in flexible electronics. Researchers have developed a technique to harvest 2-inch diameter wafers of 2-D material within just a few minutes. They can then be stacked together to form an electronic device within an hour.

Since the 2003 discovery of graphene, there has been significant interest in other types of 2-D materials as well. These materials could be stacked together like Lego bricks to form a range of devices with different functions, including operating as semiconductors...

Mechanical properties of atomically thin boron nitride and the role of interlayer interactions. Nature Communications, 2017; 8: 15815 DOI: 10.1038/ncomms15815

A stretchy miracle material has been discovered that could be used to create highly resistant smart devices and scratch-proof paint for cars. Led by Dr Elton Santos from the University’s School of Mathematics and Physics, an international team have found superlubricity in a few layers of graphene – a concept where friction vanishes or very nearly vanishes. They also found that a few layers of hexagonal boron nitride (h-BN) are as strong as diamond but are more flexible, cheaper and lighter...
