  1. Goals for Today: Nano-In-The-News Finish Introduction Begin NanoScience Discussion Assignments

  2. What is responsible for thecurrent nano revolution? • The tools • AFM, STM, FESEM • How about x-ray & TEM?

  3. Nano in the News! Local Dr. Frank Underdown Keweenaw Nanoscience Center Lake Linden, MI (visiting speaker in March…)

  4. What is Nanotechnology? The application of nanostructures into useful nanoscale devices. Many biological inspirations!

  5. Nanoscale science and engineering here refer to the fundamental understanding and resulting technological advances arising from the exploitation of new physical, chemical and biological properties of systems that are intermediate in size, between isolated atoms and molecules and bulk materials, where the transitional properties between the two limits can be controlled. -Mike Roco (NSF) 2001

  6. NanotechnologyHeirarchy • Bulk Chemistry/Materials (Chemistry & Physics accomplish the self-assembly) • Manufacturing (e.g. Intel) directed assembly • Nanomachines • Self Replicators (life?) Increasing Complexity (information, design)

  7. Moore’s 1st Law Gordon Moore 1965 Intel co-founder Transistor density on a chip doubles every ~18 months.

  8. Entering the Nanoscale Trouble Predicted Moore’s 1st Law 400 300 200 100 0 Chip Feature Size (nm) 1990 1995 2000 2005 2010 2015 Year

  9. Moore’s 2nd Law $50 $40 $30 $20 $10 $0 Why? Fab Cost (billions) 1990 1995 2000 2005 2010 2015 Year Note: Cost per bit is WAY down over time!

  10. Technology: Components are getting smaller and smaller. Interconnections between components are getting smaller and smaller.

  11. Assignment For Next Time • Read Ratter & Rattner chapters 1 & 2 • Look over the brochure Nanotechnology: Shaping the World Atom by Atom. • Answer questions on hand-out • 1-2 pages • (use complete sentences, • good grammar, etc.) http://www.nano.mtu.edu/documents/IWGN.Nanotechnology.Brochure.pdf
