Scientists achieve record efficiency for ultra-thin solar panels

A team co-led team by the University of Surrey has successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometre thick (1μm), convert light into electricity more efficiently than others as thin and pave the way to make it easier to general more clean, green energy.…

Programmed assembly of wafer-scale atomically thin crystals

Lego blocks, beloved by both children and adults, can be assembled into set models like space shuttles or cool buildings, but also can be used to build any new structures. Like these blocks, a new technology has been proposed to assemble atomic-sized blocks into new materials. A POSTECH research team led by Professor Cheol-Joo Kim…

Researchers engineer electrically tunable graphene devices to study rare physics: The breakthrough could lead to the development of ‘beyond-5G’ wireless technology for high-speed communication networks

An international team, co-led by researchers at The University of Manchester’s National Graphene Institute (NGI) in the UK and the Penn State College of Engineering in the US, has developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena…

New transistor could cut 5% from world’s digital energy budget: Design also poised to save space, retain memory in event of power loss

A new spin on one of the 20th century’s smallest but grandest inventions, the transistor, could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet. Following years of innovations from the University of Nebraska-Lincoln’s Christian Binek and University at Buffalo’s Jonathan Bird and…

Graphene-hBN breakthrough to spur new LEDs, quantum computing

In a discovery that could speed research into next-generation electronics and LED devices, a University of Michigan research team has developed the first reliable, scalable method for growing single layers of hexagonal boron nitride on graphene. The process, which can produce large sheets of high-quality hBN with the widely used molecular-beam epitaxy process, is detailed…

Chemical synthesis: Golden wedding for molecules

In chemistry, there are structures that are particularly stable, such as the so-called “benzene ring” consisting of six interconnected carbon atoms. Such rings form the structural basis for graphite and graphene, but they also occur in many dyes — such as the jeans dye indigo and in many drugs such as aspirin. When chemists wanted…
