An international team of researchers (China, USA – University of Nebraska, UC Berkeley) has developed a simple NEM switch by exploiting a switchable nanocrack controlled by an electric field in a metallic alloy-ferroelectric heterostructure. The open and closed states of the crack are programmed under a cyclic electric field. The crack-based complementary nanoelectromechanical (CNEM) switches are leveraged to construct energy-efficient and high-density reconfigurable computing. The device integrates the advantages of ferroelectric and NEM switch, such as nonvolatility, a quasi-zero OFF-state leakage current and a low operating voltage. Complementary switching enables the device to operate as a CMOS inverter in a simple manner. Thus, the device can readily implement programmable routings…read more. TECHNICAL ARTICLE 1 , 2Â
