  1. STM Scanning Tunneling Microscope What is a Nanometer? (Activity) Developed by Malory M. Peterson, Summer 2006 Nanotechnology Grant National Science Foundation #0532516

  2. Let’s Start by Reviewing Size • Take a look at the meter stick that is provided. (Your colors may vary from the ones on the example). • The whole stick (all colors) is one meter long.

  3. Decimeter • 1/10 of a meter is represented by the blue, pink, and green end. • 1/10 of a meter is called a decimeter.

  4. Centimeter • 1/10 of a decimeter is represented by the pink and green. • 1/10 of 1/10 is 1/100. • 1/100 of a meter is called a centimeter.

  5. millimeter • If we take just the green section that is 1/10 of 1/10 of 1/10. • This is also 1/10 of 1/100, or 1/10 of a millimeter. • Also, 1/1000 of a meter. • This is called a millimeter

  6. Review • We have just divided the meter stick into 10ths. • We did this 3 times and ended up with millimeters.

  7. micrometer • Imagine we took just the green millimeter and divided that into 10ths three times, like we did before. • This would give us something very small. • This would be 1/1,000,000 of a meter or a micrometer.

  8. nanometer • If we took that micrometer and divided it into tenths, three times, we would get something on the atomic level. • This is one billionth (1/1,000,000,000) of a meter. • This is a nanometer

  9. STM • The STM images on the nanometer scale. • This would be the same as taking a meter stick and dividing it into ten pieces 9 times! • This is why the nanometer is symbolized by 10-9. • 10-9 meters can also be written as .000000001 meters or 1 E-9meters. • Atoms and molecules can only be “seen” on the nanometer scale.
