Solve the Graphene Bend Puzzle – "Everyone disagreed, they were all correct"

Representation of a bend in bilayer graphene. Credit: Blanka Janicek, Pinshane Huang Lab New research from University of Illinois engineers combines atomic-level experiments with computer modeling to determine how much energy is needed to bend multilayer graphene – a question Scientists escaped since graphene was first isolated. The results were published in the journal Nature Materials of November 11, 2019. …

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. Picture credits: …

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. …
