In a first, scientists at Columbia University in New York and the University of ...

Moiré superlattices are periodic patterns formed when two or more thin semiconducting layers are stacked with a small twist angle or lattice mismatch. When 2D materials form these patterns, their ...

(Nanowerk News) Future optical communication that's vastly more reliable and faster than what's commonly available today will require new technology. Modern communication is based on charge transfer, ...

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are ...

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 ...

After nearly a century of probing the nature of tiny, ephemeral objects called excitons, researchers finally managed to image the structure, hinting at the true location of an electron. The findings ...

Researchers have created an even more exotic form of the exciton-polariton, one which has a defined quantum spin that is locked to its direction of motion. Depending on the direction of their spin, ...

AMES, Iowa – Zhe Fei pointed to the bright and dark vertical lines running across his computer screen. This nano-image, he explained, shows the waves associated with a half-light, half-matter ...

Organic semiconductors are materials that find applications in various electronic devices. Exciton binding energy is an important attribute that influences the behavior of these materials. The solid ...
