A new paper describes the first direct observation of a long-hypothesized but elusive phenomenon called 'negative capacitance'. The work describes a unique reaction of electrical charge to applied voltage in a ferroelectric material that could open the door to a radical reduction in the power consumed by transistors and the devices containing them.

The new antennas look like pyramids, rather than the more commonly used straight pillars. The pyramid shape enhances the interference between the magnetic and electric fields of light. This makes the pyramid-shaped antenna capable of enhancing light emission and beaming different colours of light towards opposite directions.
