Gallium nitride (GaN) light-emitting-diode (LED) technology has been the revolution in
modern lighting. In the last decade, a huge global market of efficient, long-lasting, and …

The disinfection industry would greatly benefit from efficient, robust, high-power deep-
ultraviolet light-emitting diodes (UV–C LEDs). However, the performance of UV–C AlGaN …

The light output of deep ultraviolet (UV-C) AlGaN light-emitting diodes (LEDs) is limited due
to their poor light extraction efficiency (LEE). To improve the LEE of AlGaN LEDs, we …

We report on III-nitride-based micro-light-emitting diodes (µLEDs) operating at 450 nm
wavelength with diameters down to 2 µm. Devices with a standard LED structure followed by …

We demonstrate a thin-film flip-chip (TFFC) process for LEDs grown on freestanding c-plane
GaN substrates. LEDs are transferred from a bulk GaN substrate to a sapphire submount via …

We report on the light extraction efficiency of III-Nitride violet light-emitting diodes with a
volumetric flip-chip architecture. We introduce an accurate optical model to account for light …

Angular distribution of polarized light and its effect on light extraction efficiency (LEE) in
AlGaN deep-ultraviolet (DUV) light-emitting diodes (LEDs) are investigated in this paper. A …

Discovering ways to increase the LED light extraction efficiency (LEE) should help create the
largest performance improvement in the power of UV AlGaN LEDs. Employing surface …

We discuss the unambiguous detection of Auger electrons by electron emission (EE)
spectroscopy from a cesiated InGaN/GaN light-emitting diode (LED) under electrical …

Laser lighting systems can take many form factors for applications, such as spotlighting,
general illumination, or decorative lighting. The use of lasers in conjunction with phosphors …
