  1. Introduction to Nanotechnology Alberto Quiñonez, Ph.D. Professor Electronics and Advanced Technologies Austin Community College 1

  2. Objective The purpose of this module is to introduce the emerging nanotechnology field to novices of nanotechnology. 2

  3. Topics • Nanotechnology Terms and Definitions • History of Nanotechnology • Current and Future Trends, Research and Applications 3

  4. Preface Is nanotechnology the gateway to the future for human beings on Earth? Figure 1.1: Where does your imagination take you? 4

  5. Emergence “…its arsenal includes nanotechnological transjectors…It can control other machines.” Figure 1.2: A nanocar made from a single molecule. Figure 1.3: Arnold Schwarzenegger’s character mentions nanotechnology in “The Terminator 3” movie. 5

  6. Nanotechnology Language Yow! • Nanobio • Nanodots • Nanowires • Nanoelectronics • Nanobots • Nanomaterials • Nanochondria Figure 1.4: Searching for nanotechnology. 6

  7. Definition “Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.” “Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.” National Nanotechnology Initiative, 2007 7

  8. Scale of Things—Nanometers Figure 1.5: National Nanotechnology Initiative. 8

  9. Internships Figure 1.6: Sematech nanoscholar interns of Texas. 9

  10. Brief History The concepts of nanotechnology are not new to nature or to mankind. An early example of a manmade nanoprocess is stained glass. Figure 1.7: Stained glass windows. Figure 1.8: Picture of gold nano particles. 10

  11. Brief History, Continued • Birth of Nanotechnology • Professor Taniguchi of Tokyo Science University used the word “nanotechnology” to describe the science and technology of processing or building parts with nanometric tolerances. • A nanometer is a unit of length in the metric system, equal to one billionth of a meter. Figure 1.9: Tokyo Science University. Figure 1.10: Equivalent Units 11

  12. Brief History, Continued • Dr. Richard P. Feynman • “Why cannot we write the entire 24 volumes of the Encyclopedia Britannica on the head of a pin?” • Dr. Richard Feynman, one of America’s most notable physicists, 1918-1988. Figure 1.11: Richard Feynman. 12

  13. Brief History Continued, • Dr. Feynman, Continued • “The problems of chemistry and biology can be greatly helped if our ability to see what we are doing, and to do things on an atomic level, is ultimately developed – a development which I think cannot be avoided.” Surely You’re Joking Mr. Feynman! Adventures of a Curious CharacterBy Richard Feynman Figure 1.12: Collection of reminiscences by Nobel Prize-winning physicist. 13

  14. Brief History, Continued • Atomic Scale • A computer image of the nano ice double helix. • In the nano ice image, oxygen atoms are blue in the inner helix, purple in the outer helix. Hydrogen atoms are white. Figure 1.13: A nanotechnology self-assembly process. 14

  15. More History • Eric Drexler • Coined the term “Grey Goo”…the potential problem of self-replicating and autonomous artificial intelligence machines. Engines of Creation The Coming Era of Nanotechnology By K. Eric Drexler Figure 1.14: Drexler’s book. Figure 1.15: DNA damage. 15

  16. X More History, Continued Eric Drexler, Continued Cell Repair Machines • “By working along molecule by molecule and structure by structure, repair machines will be able to repair whole cells. By working along cell by cell and tissue by tissue, they…will be able to repair whole organs…they will restore health.” - Drexler, 1986 Figure 1.16: Stylized example of targeted cell repair. 16

  17. More History, Continued • Metrology • Measurement of equipment is the cornerstone of nanotechnology. Figure 1.17: Scanning probe microscope systems from nanoscience instruments. Figure 1.18: Scanning tunneling microscope image. 17

  18. More History, Continued • Buckyballs • Three gentlemen—Harold Kroto from the University of Sussex, Robert Curl and Richard Smalley from Rice University—were awarded the Nobel Prize in Chemistry in 1996 for their discovery of a new composition of carbon, Carbon 60. Figure 1.19: Carbon-60 buckyball is shaped like a soccer ball. Figure 1.20: Example of Nobel prize diploma. 18

  19. More History, Continued • Fullerenes • Carbon 60 was named after Richard Buckminster Fuller, who went by the nickname “Bucky.” Figure 1.21: A “Buckyball.” Figure 1.22: Dome over biosphere in Montreal. 19

  20. More History, Continued • Top-Down Approach • Two approaches used in producing nanotechnology systems. Top-down method is used by computer chip manufacturers. Figure 1.23: Moore’s Law. Figure 1.24: Photolithography. 20

  21. More History, Continued • Bottom-Up Approach • Bottom-up approach to manufacturing is analogous to the way biological systems are made. Figure 1.25: An example of a molecular self assembly through hydrogen bonds. 21

  22. Summary Nanotechnology is ubiquitous and pervasive. It is an emerging field in all areas of science, engineering and technology. Welcome to NanoWorld! Figure 1.26: Robot image. 22
