Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

When the number of electrons matches host lattice sites in a material, strong interactions between electrons can cause them to arrange themselves into an orderly pattern, forming what is known as an ...

Quantum wells, fabricated through the precise layering of different semiconductor materials, create confined regions where charge carriers are restricted to two dimensions. This confinement gives rise ...

AlScN can be lattice-matched to GaN and integrated into blue light-emitting diodes as the electron blocking layer ...

Electron transfer is enhanced by minimal energetic driving force at the organic-semiconductor interface in upconversion (UC) organic light emitting diodes (OLEDs), resulting in efficient blue UC-OLEDs ...

In a study published in Nature Materials, a research team from the National University of Singapore (NUS) achieved a significant breakthrough by generating and directly observing electron-hole ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Researchers directly observed electron-hole pairs in light-emitting electrochemical cells, finding that ion-driven electric field changes affect recombination and that stable, lower-voltage fields ...

A team developed a novel method to successfully visualise electron-hole crystals in an exotic quantum material. Their breakthrough could pave the way for new advancements in computing technologies, ...

Electron transfer is an elementary process in which an electron is transferred or relocated from a donor molecule or atom to another such entity, called the acceptor. This process is fundamental to ...
