Cambridge University inkjet prints graphene-hBN FETs on textiles

Nov 08, 2017

Researchers from Cambridge University have demonstrated how graphene and other related 2D materials (namely hBN) can be directly printed onto textiles to create fully inkjet-printed dielectrically gated field effect transistors (FETs) with solution processed 2D materials.

According to the team, these devices are washable, flexible, cheap, safe, comfortable to wear and environmentally-friendly, essential requirements for applications in wearable electronics. The team also demonstrated the first reprogrammable memories, inverters and logic gates with solution processed 2D materials by coupling these FETs together to create integrated circuits, the most fundamental components of a modern-day computer.

Columbia researchers observe exotic quantum particle in bilayer graphene

Scientists from Columbia University have reportedly proven a 30-year-old theory called "the even-denominator fractional quantum Hall state" and established bilayer graphene as a promising platform that could lead to quantum computation.

The team observed an intensely studied anomaly in condensed matter physics—the even-denominator fractional quantum Hall (FQH) state—via transport measurement in bilayer graphene. “Observing the 5/2 state in any system is a remarkable scientific opportunity, since it encompasses some of the most perplexing concepts in modern condensed matter physics, such as emergence, quasi-particle formation, quantization, and even superconductivity,” the team says. “Our observation that, in bilayer graphene, the 5/2 state survives to much higher temperatures than previously thought possible not only allows us to study this phenomenon in new ways, but also shifts our view of the FQH state from being largely a scientific curiosity to now having great potential for real-world applications, particularly in quantum computing.”

Versarien to supply graphene to the CPI

Sep 19, 2017

Versarien LogoThe advanced materials engineering group Versarien announced that it has won a tender for the ongoing supply of nanomaterials to the Centre for Process Innovation. Versarien will supply up to 1.2 kilograms of graphene in a variety of forms to the CPI, in addition to hexagonal layer boron nitride.

Neill Ricketts, chief executive of Versarien, said: "We are very pleased to have been successful in all the tenders we entered into to supply the CPI with our nanomaterials after a competitive process". "For Versarien this is an important route for the commercialization of products enhanced by graphene and other related materials", "We continue to receive record levels of enquires from potential purchasers of our products globally and look forward to making further announcements as appropriate," Ricketts said.

A device made from graphene and boron nitride shows unprecedented promise for spintronics applications

Aug 16, 2017

Researchers from the University of Groningen developed a device made by 2D sheets of graphene and Boron-Nitride that showed unprecedented spin transport efficiency at room temperature.

Graphene-BN device with high spin transport efficiency

The research, funded by the European Union's $1 billion Graphene Flagship, uses the single-layer graphene as the core material. The researchers say that graphene is a great material for spin transport - but the spin in the graphene cannot be manipulated. To overcome this in the device, the graphene is sandwiched between two layers of boron nitride and the whole structure rests on silicon.

Graphene and hBN used to develop a 2D RRAM memory device

Jun 01, 2017

Researchers from Soochow University in China developed a 2D RRAM device structure based on sheets of graphene and hexagonal boron nitride (hBN). The device uses a Graphene/hBN/Graphene structure and it features excellent overall fitting results.
