Researchers of the MESA+ institute, in collaboration with the company SolMateS, have developed a new type of transistor to reduce the power consumption of microchips.The basic element of modern electronics, namely the transistor, suffers from significant current leakage. By enveloping a transistor with a shell of piezoelectric material, which distorts when voltage is applied, researchers were able to reduce this leakage by a factor of five (compared to a transistor without this material). The research was performed by Buket Kaleli (now with ASML), Ray Hueting and Rob Wolters from the Semiconductor Components group. Staff from SolMateS, a University of Twente spin-off company, applied the piezoelectric layer to the transistor. The research was financially supported by the technology foundation STW.
