Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

Commercially relevant bismuth-based thin film processing

Developing materials suitable for use in optoelectronic devices is currently a very active area of research. The search for materials for use in photoelectric conversion elements has to be carried out in parallel with developing ...

Nobarrier to applications for a remarkable 2-D material

Mass production of large, uniform sheets of single-layer molybdenum disulfide, MoS2, is difficult, which limits its commercial application. A*STAR researchers have modified an existing manufacturing technique to enable the ...

Missing atoms in a forgotten crystal bring luminescence

A little-studied member of the perovskite family of materials could find use in a range of electronic devices, after researchers at KAUST discovered the secret of its strong photoluminescence.

Perovskite edges can be tuned for optoelectronic performance

In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are creating innovative 2D layered hybrid perovskites that allow greater freedom ...

Nano 'sandwich' offers unique properties

Rice University researchers have modeled a nanoscale sandwich, the first in what they hope will become a molecular deli for materials scientists.

Surprising discoveries about 2-D molybdenum disulfide

Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have used a unique nano-optical probe to study the effects of illumination on two-dimensional semiconductors at the ...
