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 ...

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 ...

Glass microparticles enhance solar cells efficiency

Scientists from ITMO University have suggested a new solar cell coating that combines features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid ...

The stacked color sensor

Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity ...

Defect-free coatings for silicon spheres

The prototype kilogram – to which all scales are calibrated to – is losing weight. International efforts are striving to redefine the base unit for measuring mass and, in future, redefine the kilogram on natural constants. ...
