Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are believed to be the first LEDs whose performance has been enhanced by the creation of an electrical charge in a piezoelectric material using the piezo-phototronic effect.

A new report from the Global Information Industry Center at the University of California, San Diego examines the projected disconnect between U.S. wireless infrastructure capacity and consumer demand. According to “Point of View: Wireless Point of Disconnect,” wireless use is growing rapidly and if present trends continue, demand will often outstrip capacity, causing congestion.

New observations could improve industrial production of high-quality graphene, hastening the era of graphene-based consumer electronics, thanks to University of Illinois engineers. By combining data from several imaging techniques, the team found that the quality of graphene depends on the crystal structure of the copper substrate it grows on. Led by electrical and computer engineering professors Joseph Lyding and Eric Pop, the researchers published their findings in the journal Nano Letters.
