LEDs are small but powerful components that light up everything from phone screens to flashlights. In this video, you'll learn how a tiny chip inside an LED converts electrical energy into light using ...

For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...

Look inside a science fiction computer, and you’ll probably see tubes and cubes that emit light. Of course, it’s for effect, ...

Abstract: This paper presents an effective on-chip integration of a GaN-based metal-oxide-semiconductor field-effect transistor (MOSFET) and an ultraviolet light-emitting diode (UV LED) on a GaN-on-Si ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

In the fight against cancer, an important field of research is the search for safe alternatives to chemotherapy and radiotherapy. These treatments attack both cancer cells and healthy cells, exposing ...

A nurse practitioner-led rapid-access clinic for patients with inflammatory bowel disease (IBD) at high risk for acute care use reduced both emergency department visits and hospitalization rates. The ...

This new development uses a phenomenon called plasmonic heating that enables more precise crystal formation. Crystals used in applications as varied as lasers, LEDs and the semiconductors used in ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...
