The photoelectric properties of MAPbI3

Organic-inorganic hybrid perovskites (OIHPs) are promising in photovoltaic energy harvesting, electro-optic detection, and all-optical conversion. Understanding the atomic structure and structural instability of OIHPs is ...

Improvements in microscopy home in on biology's elusive details

In the late 1600s, the Dutch tradesman Anthoni van Leeuwenhoek began investigating the world of the very small using the first microscope, discovering a riotous world of protists, bacteria, and other previously unseen organisms. ...

Revealing the secrets of ground beetle wing casings

The striking colors of many creatures in nature result from their structures at a microscopic or even nanoscopic level. A good example of this is the metallic coloring of certain beetles. Researchers have paid increased attention ...

Wannier-Stark localization achieved in polycrystals

Scientists from Paderborn University, the Max Planck Institute for Polymer Research and the University of Konstanz have succeeded in achieving a rare quantum state. They are the first to have demonstrated Wannier-Stark localization ...

LED material shines under strain

Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more energy as heat instead ...
