Scientists obtain a hexagonal modification of silicon

A team of scientists from Lobachevsky University (Nizhny Novgorod, Russia) has obtained a material with a new structure for applications in next-generation optoelectronics and photonics. This material is one of the hexagonal ...

Graphene takes a step toward renewable fuel

Using the energy from the sun and graphene applied to the surface of cubic silicon carbide, researchers at Linköping University, Sweden, are working to develop a method to convert water and carbon dioxide to the renewable ...

Atoms use tunnels to escape graphene cover

Graphene has held great potential for practical applications since it was first isolated in 2004. But we still don't use it in our large-scale technology, because we have no way of producing graphene on an industrial scale. ...

A simple method etches patterns at the atomic scale

A precise, chemical-free method for etching nanoscale features on silicon wafers has been developed by a team from Penn State and Southwest Jiaotong University and Tsinghua University in China.

Integrating optical components into existing chip designs

Two and a half years ago, a team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University announced a milestone: the fabrication of a working microprocessor, built using only existing ...

Sharpening the X-ray view of the nanocosm

A novel lens offers scientists the sharpest X-ray images yet from the nano world. The device is made from alternating layers of tungsten carbide and silicon carbide and can focus hard X-rays into a spot of less than ten nanometers ...
