Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

At-home light-emitting diode (LED) devices are effective for treating acne, according to a research letter published online March 5 in JAMA Dermatology. Sherry Ershadi and John S. Barbieri, M.D., from ...

Semiconductor announced that superluminescent light-emitting diodes (SLEDs) from its photonics portfolio have completed final space qualification testing and have been selected for use in the ...

The first part of our series to explain “ideal diodes” in the small-signal domain and to contrast them with those found in the power domain. The intent of this series is to illustrate the “ideal” ...

The third part of our series to explain “ideal diodes” in the small-signal domain and to contrast them with those found in the power domain. In the power domain high efficiency is critical. Power ...

A phone, a laptop, a charger and a digital thermometer all do different jobs, but they rely on many of the same electronic building blocks. Resistors control currents and voltages. Capacitors and ...

Members can download this article in PDF format. Power systems employ diodes to perform a variety of functions. For example, diodes can protect against damage due to power-source reverse-polarity ...
