Understanding high efficiency of deep ultraviolet LEDs

Steps that form during LED fabrication improve their efficiency by creating tiny paths of electric current.

Magnetization reversal achieved at room temperature using only an electric field

Scientists achieved magnetization reversal in cobalt-substituted bismuth ferrite by applying only an electric field. Such an effect had been sought after for over a decade in order to make new types of low-power-consumption magnetic memory devices.

A tip for future nanoscale sensing

The tiny diamond pyramid tips used for atomic force microscopy may also prove to be highly useful for nanoscale, quantum sensing.
