Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling ...

A research team has discovered a unique quantum state at the interface between organic materials and two-dimensional semiconductors. Faster, more efficient, and more adaptable technologies are widely ...

Single layers of transition metal dichalcogenides are two-dimensional (2D) direct-bandgap semiconductors with degenerate, but inequivalent, ‘valleys’ in the electronic structure that can be ...

Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and ...

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 ...

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 demonstrated an OLED that uses singlet fission to boost the percentage of excitons created per pair of electrical charges to over 100 percent. This increase of light-producing ...

Researchers from the University of Tsukuba and collaborating partners have observed fine-scale exciton dynamics in atomically thin layered materials. This basic study for future optical communications ...
