UAB presentation

The group of Micro and Nanoelectronic Devices belongs to the Department of Electronic Engineering of the Universitat Autònoma Barcelona (Spain) and has a large and distinguished experience in the field of nanoelectronic devices, both  ultimate CMOS devices (More Moore domain) and also emerging devices that take advantage of materials properties at the nanoscale (Beyond CMOS domain). Its activities cover the device concept, modeling, simulation, characterization and reliability. The group has built the required experimental facilities to carry out this research.
