Brightening perovskite LEDs with photonic crystals

All inorganic cesium lead halide perovskite semiconductors exhibit great potential for nanolasers, light emitting diodes and solar cells due to their unique properties, including low threshold, high quantum efficiency and ...

Iron-rich lamellae in a semiconductor

There is often a pronounced symmetry when you look at the lattice of crystals: It doesn't matter where you look—the atoms are uniformly arranged in every direction. This behavior would also be expected of a crystal, which ...

Controlling the crystal structure of gallium oxide

A simple method that uses hydrogen chloride can better control the crystal structure of a common semiconductor and shows promise for novel high-powered electronic applications.

Stretching to perfection of 2-D semiconductors

Compressing a semiconductor to bring atoms closer together or stretching it to move them farther apart can dramatically change how electricity flows and how light is emitted. Scientists found an innovative way to compress ...

Ultrashort light pulses for fast 'lightwave' computers

Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics.

Organic crystals allow creating flexible electronic devices

Scientists from the faculty of physics of the Moscow State University have grown organic semiconductor crystals that can reduce the cost of creating light, flexible and transparent light-emitting electronic devices. The researchers, ...
