3. The Nanoscale 1-100 nanometers Scanning tunneling microscope. Size dependent properties!

4. What is Nanotechnology? Engineering Exploitation Two approaches:  Bottom up  Top down

5. Beginnings Richard Feynman  “Father” of nanotechnology “There’s Plenty of Room at the Bottom”  December 29, 1959 Term coined by Norio Taniguchi Development of the STM

6. The Scanning Tunneling Microscope No light. Scans the surface of sample. Movement is monitored. Image is generated.

7. IBM’s 12-atom Bit Used bottom up approach Utilized STM Magic number 12 Measure magnetism to determine bit value 83,000 times more space efficient
