Silicon as a new storage material for the batteries of the future

Longer life times, larger ranges and faster rechargingā€”developments such as electric mobility or the miniaturisation of electronics require new storage materials for batteries. With its enormous storage capacity, silicon ...

Next generation devices get boost from graphene research

(PhysOrg.com) -- Researchers in the Electro-Optics Center (EOC) Materials Division at Penn State have produced 100 mm diameter graphene wafers, a key milestone in the development of graphene for next generation high-power, ...

Team builds first quantum cascade laser on silicon

A team of researchers from across the country, led by Alexander Spott, University of California, Santa Barbara, USA, have built the first quantum cascade laser on silicon. The advance may have applications that span from ...

New plasma transistor could create sharper displays

(PhysOrg.com) -- By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive ...

Graphene: New electronics material closer to commercial reality

(PhysOrg.com) -- Researchers have developed a method for creating single-crystal arrays of a material called graphene, an advance that opens up the possibility of a replacement for silicon in high-performance computers and ...

New organic lasers one step closer to reality

New research could make lasers emitting a wide range of colors more accessible and open new applications from communications and sensing to displays.

Researchers 'iron out' graphene's wrinkles

From an electron's point of view, graphene must be a hair-raising thrill ride. For years, scientists have observed that electrons can blitz through graphene at velocities approaching the speed of light, far faster than they ...
