Visualization of quantum dots in bilayer graphene using scanning tunneling microscopy and spectroscopy reveals a three-fold symmetry. In this three-dimensional image, the peaks represent sites of high amplitude in the waveform of the trapped electrons.

The LDG/MIP-based electrochemical sensor sensitively and selectively detects BPA in water samples. Credit: © 2020 KAUST A simple method developed at KAUST uses laser beams to create grapheneelectrodes that have better performance than those produced through older methods. Electrodes consisting of graphene, an atypical form of carbon, may transform the way […]

Stacking monolayer and bilayer graphene sheets with a twist leads to new collective electronic states, including a rare form of magnetism. Credit: Columbia University Twisting a monolayer and a bilayer sheet of graphene into a three-layer structure leads to new quantum mechanical states. Since the discovery of graphene more than 15 years […]

The new SQUID is made up of a stack of two-dimensional materials, including two graphene layers separated by a thin film of boron nitride. Credit: University of Basel, Department of Physics David Indolese, a Physicist at the University of Basel, shortly explains the new SQUID – a minuscule instrument able […]

Injecting calcium into graphene creates a superconductor, but where does the calcium actually end up? Credit: FLEET ‘Floating’ Graphene on a Bed of Calcium Atoms Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go? Adding calcium to a composite graphene-substrate structure creates a high transition-temperature (Tc) superconductor. […]

Researchers led by Katja Nowack, assistant professor of physics, created this micron-scale Hall-effect sensor by sandwiching graphene between sheets of hexagonal boron nitride, resulting in a device that operates over a greater temperature range than previous Hall sensors.

New roll-to-roll production method could enable lightweight, flexible solar devices and a new generation of display screens. A new way of making large sheets of high-quality, atomically thin graphenecould lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics. The new manufacturing process, which […]
