Exploring Fabrication - Electroplating (NanoDays 2014)

"Exploring Fabrication - Electroplating" is a hands on activity in which visitors coat a nickel coin with copper using the electroplating process. They learn that electroplating can deposit nanometer-thin layers of materials.

Electroplating (High School curriculum lesson)

Students will create thin layers of copper and nickel in an electrochemical reaction to understand how an electric current passed through an ionic solution will result in a chemical reaction which will separate materials. In addition students will also explore the various parameters effecting deposition, morphology, and thickness of the film to be deposited.

Scientific Image - Quantum Corral (side view)

The corral is an artificial structure created from 48 iron atoms (the sharp peaks) on a copper surface. The wave patterns in this scanning tunneling microscope image are formed by copper electrons confined by the iron atoms. Don Eigler and colleagues created this structure in 1993 by using the tip of a low-temperature scanning tunneling microscope (STM) to position iron atoms on a copper surface, creating an electron-trapping barrier. This was the first successful attempt at manipulating individual atoms and led to the development of new techniques for nanoscale construction.
