Atom swapping could lead to ultra-bright, flexible next generation LEDs
Ella Maru Studio
An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials which are flexible and can be printed using ink-jet techniques. The researchers, led by the University of Cambridge and the Technical University of Munich, found that by swapping one out of every one thousand atoms of one material for another, they were able to triple the luminescence of a new material class of light emitters known as halide perovskites.

The University of Cambridge is creating a new research initiative, bringing together physicists, chemists, biologists, mathematicians, and earth scientists to answer fundamental questions on the origin and nature of life in the Universe.
Led by 2019 Physics Nobel Laureate Professor Didier Queloz, the Cambridge Initiative for Planetary Science and Life in the Universe will be the driving force for the development of a new Cambridge research community investigating life in the Universe, from understanding how it emerged on Earth to examining the processes that could make other planets suitable for life.
The initiative comes at a crucial moment in science, as scientists are able to study exoplanets – planets orbiting stars other than our Sun – in ever-greater detail, and outstanding progress is being made in prebiotic chemistry: carefully-regulated laboratory experiments to recreate the conditions when life first formed on Earth.

By bringing together chemists, geologists, biologists, and astrophysicists to work toward a common goal, we can exploit the full potential of this exciting new field of research, bringing us closer to understanding life in the Universe and finding life beyond Earth

Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick.
The results, reported in the journal
Physical Review Letters, could be used to design new types of materials and quantum technology devices. The researchers, from the University of Cambridge, captured the movement of the atoms at speeds that are eight orders of magnitude too fast for conventional microscopes.
Two-dimensional materials, such as graphene, have the potential to improve the performance of existing and new devices, due to their unique properties, such as outstanding conductivity and strength. Two-dimensional materials have a wide range of potential applications, from bio-sensing and drug delivery to quantum information and quantum computing. However, in order for two-dimensional materials to reach their full potential, their properties need to be fine-tune
