What is nanotechnology?
• Nanotechnology is science, engineering, and
technology conducted at the nanoscale, which is about 1 to 100
nanometers.
• December 29, 1959: “There’s Plenty of Room at the Bottom”
Physicist Richard Feynman, the
father of nanotechnology.

Modern nanotechnology
• It wasn't until 1981, with the development of the scanning tunneling
microscope that could "see" individual atoms, that modern
nanotechnology began.
• Nanotechnology is the engineering of functional systems at the
molecular scale.

Typical questions
• How does one make a nanometer sized object?
• How do you make many (identical) nanometer sized objects?
• How do the optical and electrical properties of this nanoscale object change with size?
• How does its optical and electrical properties change with its “dimensionality”?
• How do charges behave in nanoscale objects?
• How does charge transport occur in these materials?
• Do these nanoscale materials poses new and previously undiscovered properties?
• Are they useful?
