has announced a significant milestone in silicon photonics with the successful demonstration of electrically driven GaAs-based multi-quantum-well nano-ridge laser diodes fully, monolithically ...

“While GaAs is an excellent material and generally ... NREL also measured its triple junction quantum well cells under the light spectrum they would have to work with outside of Earth’s ...

Both bulk and quantum-well-based sources do not function well ... Just as water forms droplets on a newly waxed car, so does InAs on a GaAs substrate because of the large lattice mismatch between ...

First, we observed the basic effect of 2PE in a bulk GaAs semiconductor that was optically ... device — an electrically driven LED-like quantum-well-based device that emits two photons when ...
