Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.

Joined nano-triangles pave the way to magnetic carbon materials

June 2, 2020 sarah Jonas Graphene, Magnets, Quantum Mechanics

Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a “quantum entanglement” of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal “Angewandte Chemie”.

Columbia Researchers Develop New Method to Isolate Atomic Sheets and Create New Materials

February 20, 2020 sarah Jonas 2D Nanomaterials, Graphene, Semiconductor

Columbia researchers have invented a new method—using ultraflat gold films—to disassemble vdW single crystals layer by layer into monolayers with near-unity yield and with dimensions limited only by bulk crystal sizes. The monolayers have the same high quality as those created by conventional “Scotch tape” exfoliation, but are roughly a million times larger. They can be assembled into macroscopic artificial structures, with properties not easily created in conventionally grown bulk crystals.
