High-temperature superfluidity in double-bilayer graphene.
Exciton bound states in solids between electrons and holes are predicted to form a superfluid at high temperatures. We show that by employing atomically thin crystals such as a pair of adjacent bilayer graphene sheets, equilibrium superfluidity of electron-hole pairs should be achievable for the first time. The transition temperatures are well above liquid helium temperatures. Because the sampl...
متن کاملFormation and Transport of Correlated Electronic States at Room Temperature in Graphene Bilayers
We propose a combination of methods to investigate the characteristics of electron-hole bilayer graphene at spontaneous coherence using novel path integral Monte Carlo and Green's function based methods at room temperature. Using the presented numerical techniques at room temperature, we find a sharply peaked differential tunneling conductance and quasiparticle paths which wind around our solut...
متن کاملRoom-temperature ferromagnetism of graphene.
Aiming at molecular-based magnets, ferromagnetism of pure carbon-based materials is fundamentally and technologically extremely important for many applications. While it is still not fully understood, many recent theoretical works have suggested that one-atom-thick two-dimensional graphene materials may show ferromagnetism due to the existence of various defects or topological structures as the...
متن کاملRoom-temperature Magnetic Ordering in Functionalized Graphene
Despite theoretical predictions, the question of room-temperature magnetic order in graphene must be conclusively resolved before graphene can fully achieve its potential as a spintronic medium. Through scanning tunneling microscopy (STM) and point I-V measurements, the current study reveals that unlike pristine samples, graphene nanostructures, when functionalized with aryl radicals, can susta...
متن کاملRoom-temperature quantum Hall effect in graphene.
The quantum Hall effect (QHE), one example of a quantum phenomenon that occurs on a truly macroscopic scale, has attracted intense interest since its discovery in 1980 and has helped elucidate many important aspects of quantum physics. It has also led to the establishment of a new metrological standard, the resistance quantum. Disappointingly, however, the QHE has been observed only at liquid-h...
