How electrons interact with other electrons at quantum scale in graphene affects how quickly they travel in the material, leading to its high conductivity. Now, Natália Menezes and Cristiane Morais Smith from the Centre ...
Though they're touted as ideal for electronics, two-dimensional materials like graphene may be too flat and hard to stretch to serve in flexible, wearable devices. "Wavy" borophene might be better, according to Rice University ...
Graphene is a single-atomic carbon sheet with a hexagonal honeycomb network (Fig. 1). Electrons in graphene take a special electronic state called Dirac-cone where they behave as if they have no mass. This allows them to ...
In 2013, MIT physicists showed for the first time that shining powerful mid-infrared laser light on solid bismuth selenide produces Floquet-Bloch states, which are characterized by replicas of electronic energy states inside ...
The Dirac cone, named after British physicist Paul Dirac, started as a concept in particle and high-energy physics and has recently became important in research in condensed matter physics and material science. It has since ...
A group of scientists from Russia, the USA and China have predicted the existence of a new two-dimensional carbon material via computer generated simulation, a "patchwork" analogue of graphene called phagraphene. The results ...
When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...
Graphene, a two-dimensional (2D) honeycomb sheet composed of carbon atoms, has attracted intense interests worldwide because of its outstanding properties and promising prospects in both basic and applied science. The great ...
Scientists have produced a new map of the Moon's most unusual volcano showing that its explosive eruption spread debris over an area much greater than previously thought.
(Â鶹ÒùÔº) —As computer chips continue to get smaller and more powerful, the field of electronics is approaching some severe limits.
