Electron devices

Activities

The research is focused on the design, experimental characterization and numerical modeling of innovative electronic devices.
  • Non-volatile memories:
    Scaling of the Flash technology resulted today in arrays of memory devices with deca-nanometer size. The research activity is devoted to the experimental and modeling investigation of (i) those fundamental effects limiting device reliability, (ii) optimization of the memory operating conditions to match the reliability requirements. On the othe hand, as scaling of mainstream memories are reaching the ultimate physical limitations, alternative memory approaches are being investigated. The lab is involved in pioneering research programs on resistive memories using for storage novel concepts and materials.
  • Organic semiconductor devices:
    Organic electronics is attracting a growing interest due to peculiar characteristics of organic semiconductors, such as easly processability, mechanical flexibility, chemical tailoring of electronic properties and electroluminescence in the visible range. The lab activity is addressing electrical characterization of organic devices (transistors, photodetectors and memories), as well as modeling their transport and optoelectronic properties.
