Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up ...
Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and handle information in the future. But how can these expectations be met? A ...
Quantum physicists are edging closer to a kind of controlled transmutation, not of lead into gold, but of one electronic reality into another. By steering exotic entities called excitons, researchers ...
SUNNYVALE, Calif.--(BUSINESS WIRE)--NTT Research, Inc., a division of NTT (TYO:9432), today announced that scientists from its Physics & Informatics (PHI) Lab have achieved quantum control of exciton ...
Ultrafast measurements reveal how light energy moves across two dimensional and organic semiconductor interfaces, enabling rapid transfer that could improve future optoelectronic devices. (Nanowerk ...
Coulombic attraction between a negatively charged electron and a positively charged hole form excitons. The photoexcitation in semiconductors exhibits a spectrally narrow linewidth resulting in ...
The atomic lattice structure of the layered magnetic semiconductor chromium sulfide bromide (CrSBr) have magnetic moments, or spins, that align with each other and alternate on each layer. This ...
Researchers have found a way to make “dark excitons”—normally invisible quantum states of light—shine dramatically brighter by trapping them inside a tiny gold-nanotube optical cavity. This ...

Quantum 'alchemy' made feasible with excitons
What if you could create new materials just by shining a light at them? To most, this sounds like science fiction or alchemy, but to physicists investigating the burgeoning field of Floquet ...
