A hydrothermally synthesized CeO2/graphitic carbon nitride heterostructure delivers 675 F g−1 capacitance, 99.7% retention ...

The function of an LED is to emit light when the device is forward biased within its operating range, and it’s known by most people that an LED can also operate as a photodiode. Perhaps some readers ...

Inductor-inductor-capacitor (LLC) resonant converters have a couple of appealing characteristics for applications requiring an isolated DC/DC converter such as minimal switching losses, no reverse ...

Tracking an aspect of your health is one of the most popular applications for wearables these days. In the U.S. alone, 44% of Americans own devices specifically for this purpose, according to one ...

Photodiodes are a two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination. Photodiodes are used for the detection of ...

Varactor diodes are two-terminal electronic components that are designed to provide voltage-controlled capacitance when operated under reverse bias. These simple semiconductors are PN junctions with a ...

High voltage! The sight of this familiar warning jars the senses and triggers caution in even the most experienced engineer. High voltage is a relative term, however, warnings are similar whether ...
