Graphene from gases for new, bendable electronics

Graphene from gases for new, bendable electronics. Flexible, translucent and ultrathin, layers of carbon atoms called graphene are also excellent electrical conductors that could find use in flexible computer displays, molecular electronics and new wireless communications. Making high-quality graphene sheets is usually a slow, painstaking process, but now several research groups have discovered ways to make patterned graphene circuits using techniques borrowed from microchip manufacturing, which can be scaled up for mass production. Layers of graphene — carbon atoms arranged in a chicken-wire pattern one atom thick — can be manually peeled away from the graphite in pencils using adhesive tape. In contrast, the new technique causes carbon atoms in a vapor of hydrocarbons to settle onto a nickel surface and arrange into graphene’s characteristic pattern of hexagons. Using standard chip-making techniques, circuit designs are etched into the nickel surface. As the graphene layer

Atomtronics trying to replace Electronics....Using Ultracold Atoms Instead of Electrons, Atomtronics Could Revolutionize Computing

Atomtronics trying to replace Electronics... We all have heard of electronics, mechatronics and maybe even spintronics, but the latest buzzword doing the rounds of physics labs is atomtronics—the science of creating circuits, devices and materials using ultra-cold atoms instead of electrons Electronics is the field of electron movement in the circuits governed by the use of wires, silicon and electricity. All modern electronic devices contain transistors as the fundamental building blocks. Until recently, electronics had been based on a single property of electrons—their charge. But now physicists have begun to exploit another property—electron spin. So-called spintronics promises to revolutionise electronics because it allows information to be encoded in an entirely new way. Though electronics is bestowed with a large number of inherited advantages, but in the era of quantum electronics it is facing new challenges. Because electrons lose any possible initial quantum sta
