Watching two-dimensional materials grow

They are among the thinnest structures on earth: "two-dimensional materials" are crystals which consist of only one or a few layers of atoms. They often display unusual properties, promising many new applications in opto-electronics ...

Organic crystals twist, bend, and heal

Crystals are brittle and inelastic? A novel class of smart, bendable crystalline organic materials has challenged this view. Now, scientists have engineered a molecular soft cocrystalline structure that bends and twists reversibly ...

Cell membrane inspires new ultrathin electronic film

Japanese researchers have developed a new method to build large areas of semiconductive material that is just two molecules thick and a total of 4.4 nanometers tall. The films function as thin film transistors, and have potential ...

Polymer-graphene nanocarpets to electrify smart fabrics

Researchers from Tomsk Polytechnic University, together with their international colleagues, have discovered a method to modify and use graphene, a one-atom thin conductor of current and heat, without destroying it. Thanks ...

How to turn light into atomic vibrations

Sheet-like materials can have intriguing properties that could benefit devices from flexible electronics to solar cells. Researchers think they can customize the properties of these materials by using light pulses to rapidly ...

New method to manufacture organic solar cells

The ability to use cheap materials and simple manufacturing methods are two huge advantages of printed organic solar cells. Olle Inganäs, professor at Linköping University, is head of a research group that has now developed ...

Graphene enables high-speed electronics on flexible materials

A flexible detector for terahertz frequencies (1000 gigahertz) has been developed by Chalmers researchers using graphene transistors on plastic substrates. It is the first of its kind, and can extend the use of terahertz ...
