Physicists make graphene discoveries that could contribute to the development of superconductors

Left: This image, taken with a scanning tunneling microscope, shows a moiré pattern in "magic angle" bilayer graphene. Right: Scanning tunneling charge spectroscopy, a technique invented by the group of Professor Eva Andrei, shows correlated electrons, as shown by the alternating positive (blue) and negative (red) charge stripes formed in the "magic angle" twisted bilayer graph have left.

A graphene superconductor playing more than one tune

Graphene / boron nitride moire superlattice material consists of three atomically thin (2D) layers of graphene (gray) sandwiched between 2D boron nitride ( red and blue) are arranged. to form a repeating pattern called the moiré superlattice. The superconductivity is indicated by light green circles. Picture credits: Guorui Chen et al. / Berkeley Lab Researchers at the US Department of …

Physicists discover completely new quantum states when graphene meets

The super-thin & # 39; wonder material & # 39; Graphene has upset science for years with its amazing features, but it gets really interesting to stack that 2D nanomaterial against itself. In recent experiments, physicists in the US have found that proximity to previously unobserved quantum states results when graphene is assembled in a double-layered vertical stack – with …

Examinations show exotic quantum states in two-layer graphene

In the bilayer structure of graphene, a novel type of quasiparticle is discovered. This so-called compound fermion consists of an electron and two different types of magnetic fluxes, which are shown in the figure as blue and gold arrows. Composite fermions are able to form pairs. This unique interaction leads to the experimental discovery of unexpected new quantum Hall phenomena. …

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 …

"GO dough" makes graphene easy to shape and shape

The GO dough is very easy to process and versatile. It can be easily reshaped by cutting, squeezing, shaping and carving. Photo credits: Jiaxing Huang / Northwestern University A team from Northwestern University literally redesigns the world of graphene. The team has made graphene oxide (GO) a soft, malleable and kneadable play dough that can be shaped and reshaped into …
