Write, Read, Erase, Again And Again

Abstract:
In an advance reminiscent of the children's toy Etch A Sketch, researchers have developed a lithography method for preparing erasable nanometer-sized patterns. Similar to the plaything with which kids sketch with aluminum powder then wipe the slate clean and start over again, the new technique provides a way to prepare nanoscale metal patterns that can be erased and redrawn repeatedly.

Now, chemists at Temple University, in Philadelphia, have developed a straightforward method based on electrodeposition and atomic force microscopy that can be used to prepare closely spaced 25-nm-wide metal wires in an insulating medium.
