NDQC/NDeRC Nanotechnology Rotation

  1. 1. NANO Collaboration<br />Molecular Nano-electronics<br />
  2. 2. Computer Architecture<br /><ul><li>Computer chips are made of integrated circuits (interconnected transistors)
  3. 3. First transistor – Bell Labs 1947
  4. 4. Computer speed and storage capacity increases as more transistors are placed on a single chip
  5. 5. Through advances in technology the number of transistors that fit on a chip has doubled every two years since 1970– Moore’s Law</li></li></ul><li>Moore’s Law<br />
  6. 6. Limits of Current Technology<br /><ul><li>Etching or cutting structures in semiconductors may be reaching a size limit: immersion lithography 45nm (too large)
  7. 7. Semiconductor devices generate a lot of heat – even large cooling systems that are used today won’t be able to cool fast enough as the transistors get still smaller (packed more densely) and the heat/volume increases – the devices will melt</li></li></ul><li>New Approach<br /><ul><li>Use molecules for electronic structures rather than “etching” structures in semiconductors
  8. 8. Advantages</li></ul>Smaller structures (6nm as compared to 45nm)– faster speeds and greater storage capacity<br />Much less power – less cooling is needed<br />http://www.youtube.com/watch?v=XgqqP7yPdUQ<br />
  9. 9. Molecular Structures<br /><ul><li>We would like:</li></ul>Self assembly – structures “build themselves”<br />Surface – specified location and geometry to interface with the rest of the device<br /><ul><li>DNA Tiling: DNA Origami</li></ul>Surface chemistry to assemble structures<br />Scanning probe microscopes to see/measure features of the molecular structure<br />Prof. Marya Lieberman, PhD Candidate Valerie Goss and NANO Collaboration– Department of Chemistry & Biochemistry in Stepan Chemistry<br />
  10. 10. Professor Lieberman & Ms. Goss<br />
