Ultraviolet light emitting diodes (UV-LEDs) have rapidly evolved as a promising alternative to conventional mercury-based UV lamps in water disinfection systems. Their compact size, reduced energy ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

Ultraviolet-B (UV-B) semiconductor lasers are required for medical, biotechnology, and precision manufacturing applications; however, for a long time UV-B laser diodes have been limited to pulsed ...

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

In a breakthrough set to revolutionize the semiconductor industry, engineers have developed the world's first-of-its-kind deep-ultraviolet (UVC) microLED display array for lithography machines. This ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...
