2 Center for Nanoscale Science and Technology – NIST 2 Outline NIST at a Glance The New Center for Nanoscale Science and Technology –The Nanofab –The Research Program Quick Tour of Nanotechnology throughout NIST

3 Center for Nanoscale Science and Technology – NIST 3 The NIST Laboratories

4 Center for Nanoscale Science and Technology – NIST 4 CNST Mission and Structure Mission: To enable the development of nanotechnology –Provides both research and access to facilities –Works to solve outstanding nanoscale measurement and fabrication problems Structure: The CNST consists of a Research Program and the CNST Nanofab –The Nanofab A national facility offering convenient and economical access to expensive nanoscale measurement and fabrication tools. –The Research Program Multidisciplinary research staff operates in a highly collaborative mode

5 Center for Nanoscale Science and Technology – NIST 5 Advanced Measurement Laboratory CNST leverages the facilities of the AML – arguably the world’s most advanced laboratory – for its nanotechnology research.

6 Center for Nanoscale Science and Technology – NIST 6 The CNST Nanofab is well equipped and expanding See cnst.nist.gov for details

7 Center for Nanoscale Science and Technology – NIST 7 Research Program Developing measurement capabilities for: –Future Electronics Devices, architectures, interconnects –Nanomanufacturing and Nanofabrication Top-down and bottom-up fabrication and assembly –Energy Conversion, storage, and transport Complementary to and interactive with strong, existing NIST Laboratory programs Areas of concentration will, of necessity, change with needs

8 Center for Nanoscale Science and Technology – NIST 8 Core Competences Atomic Scale Characterization and Manipulation –Fabrication and measure the geometric and electronic structure of materials with atomic resolution using a UHV cryogenic/high magnetic field scanning tunneling microscope system. Directed Assembly –Fabrication and study the effects of templating structures on the organization of nanoscale materials and their resultant properties. Laser-Atom Manipulation –Laser control of atomic motion is used to develop new nanofabrication and nanoscale measurement methods. Nanomagnetic Imaging (SEMPA) –Use of spin polarized electrons generated in a scanning electron microscope to image magnetic structures over a large magnification range. Measurements are sensitive to less than a monolayer of magnetic material. Nanophotonics –Study of nanofabricated optical structures that confine light to wavelength-scale dimensions and to investigate light- matter interactions with near-field probing and microphotoluminescence setups. Nanoscale Transport –Device fabrication and photo-electrical probing of electronic and ionic transport properties of thin-film materials and nanoscale objects equipped with probe station, cryostats, air/ liquid /high-vacuum STM/cAFM. Nanoplasmonics –Design and nanofabrication of metal-based photonic components and metamaterials which exploit subwavelength confinement of light, for applications in information processing, metrology, and microscopy. Nanomagnet Dynamics –Fabrication and measurement of magnetization dynamics of magnetic nanostructures. Microwave spectroscopy techniques yield precise information on material and structure properties at the nanoscale NEMs, MEMs, Nanoscale Process Control (Coming soon) +
