Light-emitting diodes (LEDs) are changing the lighting and display industry and have obtained significant advances than traditional lighting sources. The traditional materials LEDs, e.g., III-V ...

PISCATAWAY, N.J., Feb. 7, 2025 /PRNewswire/ -- Laser diodes are semiconductors that generate light and amplify it using repeated reflection or 'optical feedback'. Once the light has achieved desirable ...

Energy-saving solid-state lighting and full colour displays have come along in leaps and bounds in recent years with materials that emit bright, pure colours. To create white light, we need red, green ...

Transition metal dichalcogenides (TMDs), a two-dimensional (2D) semiconductor, are promising materials for next-generation optoelectronic devices. They can emit strong light due to the large binding ...

Technion observes light-sound waves in 2D materials, first time in history The scientists sent pulses of light around the edges of these 2D materials using a ultrafast transmission electron microscope ...

Carbon nanotubes can glow brilliantly when light is absorbed by a flat sheet of atoms acting as an antenna to direct that energy into the tubes. This breakthrough might help create future tiny ...

Using an ultrafast transmission electron microscope, researchers from the Technion – Israel Institute of Technology have, for the first time, recorded the propagation of combined sound and light waves ...
