The center integrates six research thrusts in molecular based nanostructures, semiconductor-based nanostructures, device concepts and modeling, nanofabrication characterization, image and information processing, and functional systems design to address common application goals. The six thrusts comprise a multidisciplinary mix of researchers from the Departments of Electrical Engineering, Computer Science and Engineering, Chemistry and Biochemistry, Physics, and Chemical and Biomolecular Engineering.
The center has excellent on-site research facilities and capabilities including nanolithography and scanning tunneling microscopy; nanodevice and circuit fabrication; nano-optical characterization including femtosecond optics and near-field scanning optical microscopy;electrical characterization at helium temperatures and in ten tesla magnetic fields; fifty gigahertz high-speed circuit analysis; and device and circuit simulation and modeling.
Research Facilities include:
-The Notre Dame Nanofabrication Facility
-The Optoelectronics Laboratory
-The Cryogenic Characterization Laboratory
-The Nano-Optics Laboratory
-The High-Speed Circuits and Devices Laboratory
-The Device Simulation Laboratory
The center engages in a variety of research initiatives in nanoscience and electronics, such as quantum cellular automata and architectures; resonant-tunneling devices and circuits; photonic integrated circuits; quantum transport and hot carrier effects in nanodevices; optical and high-speed nano-based materials, devices, and circuits.
In the future, the Center will spearhead several new directions including the interaction of biological systems with semiconductors, and the role of non-equilibrium thermodynamics in influencing the properties of nanodevices.
A major emphasis of the center is the concept of computing with Quantum-dot Cellular Automata, which is based on encoding binary information through the charge configuration of quantum-dot cells; the QCA notion has spurned further studies into nano-based cellular architectures for information processing which embeds hierarchical functional design.
