Figure 1: Typical Isat and Irms Ratings

­Inductors function as circuit elements by reaction to current flow in the windings. Inductors are fundamentally current-driven devices, and anyone who has designed a dc-dc converter knows power inductor datasheets are covered with Irms and Isat current ratings. Picking a power inductor is all about current ratin

Into the Blue: Progress in Perovskite LEDs for Deep-Blue Light

Scanning electron microscopy image with digital photograph during operation (left) and transient absorption spectrum (right) of deep-blue emitting perovskite light-emitting diodes (LEDs) prepared by hot-antisolvent bathing.

­The deep blue of your LED display is likely produced by indium gallium nitride (InGaN), a costly substance. In the field of LEDs, researchers are seeking alternatives in a type of perovskite known as quasi-2D Ruddlesden‒Popper perovskites (2D-RPPs). 2D-RPPs have excellent optoelectronic properties – ideal fo
