Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative ...

Light-emitting diodes with an emission wavelength longer than 365 nm typically have GaN or InGaN quantum wells (QWs) in the active region, and those with shorter wavelengths in general have AlGaN QWs.

Red light therapy uses light-emitting diode (LED) technology and various wavelengths of light. Some people report that using these lights improves various conditions, but more research is needed ...

Abstract: Pd/InGaP hydrogen sensors based on the metal-oxide-semiconductor (MOS) and metal-semiconductor Schottky diodes have been fabricated and systematically studied. The effects of hydrogen ...
