Correction: Photobiomodulation: lasers vs. light emitting diodes?

Light-emitting silicon pn diodes

We report on the electrical and optical characteristics of silicon light-emitting pn diodes. The diodes are prepared by ion implantation of boron at high doses and subsequent hightemperature annealing. Under forward bias, the diodes emit infrared electroluminescence closely below the band gap of bulk Si. We present a rate-equation model for bound excitons, free excitons and free carriers which ...

Flexible vertical light emitting diodes.

Recently developed concepts in materials, manufacturing approaches and mechanics strategies open up opportunities for building optoelectronic systems with high performance, inorganic semiconductors in systems that afford exceptional levels of mechanical deformability (e.g., ability to bend and stretch), diversity in geometric layouts (e.g., large-area coverage, in dense or sparse coverages), an...
