- Top ⇨ Down: Start with the big chunk and cut away material to make
the what you want.
- Bottom ⇨ Up: Building what you want by assembling it from small
prefabricated units such as atoms and molecules.

- In 1965 Gordon Moore observed that
number of transistors per integrated circuit
was growing exponentially with time.
Doubling every 2 yrs (approximately)

- NanoLab was first run during the Aug 2003 intersession.
- Development of NanoLab is funded by the NSF NUE
- The intent is to provide an introduction to nanotechnology that is
accessible at the sophomore level.
- Does this mean that NanoLab dumbed down?
NO.
- There are many levels of understanding.
Is it necessary to be a motorcycle mechanic to ride a
motorcycle?
- Students are encouraged to pursue understanding of the material to a
level where they are comfortable.
|

|
- general hands-on experience
- Nanotechnology beyond the hype
- What is actually involved?
- An introduction to our capabilities at OU
- NanoLab uses active research facilities.
- Many of the activities you will do are based on actual ongoing
research. TAs have developed and tested the procedures so
that they will work in the time allotted.

- NanoLab depends on YOU
- Please take tell us the following (on paper)
- List your interests.
- What are some topics you would really like to cover in NanoLab?
- Do you have experience with techniques that would benefit NanoLab?
|
15
|
- The future depends on you
- We need to hear from you. What
are you interests. What did you
like? What did you not?
- Would you recommend NanoLab to your friends?
- Should NanoLab be repeated?

- distance between atoms ~3Å ~ 10–7.5 cm (3x10–8
cm ~ 100.5 x10–8 cm = 10–7.5
cm)
- # atoms/cm ~ 107.5
- # atoms/cm2 ~ (107.5)2 = 1015
- # atoms/cm3 ~ (107.5)3 = 1022.5
