Researchers make thinner films for capacitors, improve efficiency
The Autonomous University of Nuevo León (UANL), in collaboration with the University of Toulouse, Kemet Electronics and Marion Technologies, claims to have developed a way to improve the electrical efficiency of capacitors used in mobile devices such as computers, smartphones and tablets.
Professor Juan Antonio Aguilar Garib from UANL said the aim of the project was to reduce capacitor film thickness in order to allow more layers to be included in the device.
"We used a technique called tape casting and a mixture of barium titanate powder and other substances. This was emptied uniformly on a plastic surface and the excess is removed to form an ultra thin film just 3µm thick," said Prof Garib.
The process is said to be compatible with existing manufacturing techniques and the researchers believe that transfer to industry should be simple.
