Why twisted graphene is one of the year's most exciting physics stories

A moiré pattern of twisted two-ply graphene. Image: NIST Only a year ago, the scientists presented results that seemed almost too good to be true: carbon plates that were only a single atom thick assumed graphene called a pair of important physical properties, when they are rotated at exactly the right "magic" angle. When the atmosphere at the world's largest …

Laser-induced graphene becomes hard with the help

Rice University scientists have combined laser-induced graphene with a variety of materials to produce robust composites for a variety of applications. Picture credits: Tour Group / Rice University Laser-Induced Graphene (LIG), a flaky atomic carbon foam, has many interesting properties in itself, but gains new power as part of a composite material. The labs of chemist James Rice at Rice …

Physicists capture the temporal coherence of a graphene qubit

Researchers at MIT and elsewhere have recorded the "temporal coherence" of a graphene qubit – how long it maintains a particular state in which it represents two logical states simultaneously – a crucial step forward for practical quantum computing. Researchers from MIT (19459007) and elsewhere have for the first time recorded the "temporal coherence" of a graphene qubit – meaning …

Physicists record the lifetime of graphene qubits

This visualization shows graphene layers for membranes. Picture credits: University of Manchester Researchers at MIT and elsewhere have for the first time recorded the "temporal coherence" of a graphene qubit. This means how long a special state can be maintained, by which two logical states can be represented simultaneously. The demonstration, which used a new graphene-based qubitite, is a crucial …

Graphene Quantum dots structure could have significant significance in quantum computing

Scientists at the National Institute for Standards and Technology (NIST) succeeded in using magnetic fields to create a graphene quantum dot structure that encompasses electrons within a series of rings within graphene. The resulting structure, which the researchers said resembled a "wedding cake", could be of great importance and applicability in the quantum computer. This experiment confirmed the interactions of …

"Topological" graphene nanoribbons capture electrons for new quantum materials – ScienceDaily

Scientists experiment with narrow strips of graphene, called nanoribbons, in the hope of producing new, cool electronic devices. Scientists at the University of California, Berkeley, have discovered another potential role for them: as nanosurfaces with possible applications in quantum computers. Graphene, a carbon layer located in a rigid honeycomb lattice similar to chicken wire, has interesting electronic properties. But when …

Researchers are improving the conductivity of graphene, making solar technology more promising

Researchers at the University of Kansas have combined one graphene layer with two other atomic layers (molybdenum diselenide and tungsten disulfide), extending the lifetime of excited electrons to graphene several hundred times , Credit: Matthew Bellus In 2010, the Nobel Prize for Physics went to the discoverers of graphene. Graphene, a single layer of carbon atoms, has properties that are …
