Abstract: Large-area LED signage backlighting systems require power supplies to provide constant voltage to multiple LED modules connected in parallel, each with a built-in LED current regulator to ...

Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought ...

PQL, a commercial lighting manufacturer, has recalled 186,520 High Bay Linear LED light fixtures because they can be a fire ...

Abstract: P-metal geometry has a significant impact on chip current spreading, which, in turn, affects the optoelectronic characteristics of the devices. We designed and fabricated a series of $37~\mu ...
