Transport VI


"Transport VI," from the Heller Gallery

"Transport VI," from the Gallery of Eric J. Heller.

An explanation of the image, as taken from Heller Gallery:
The Transport series renders electron flow paths in a "two dimensional electron gas" (2DEG), inspired by the experiments of Mark Topinka, Brian Leroy and professor Robert Westervelt of Harvard University. Our group was responsible for the theoretical treatment of the problem, primarily Scot Shaw, and myself.

"Transport VI" is based on the actual electron flow patterns for electrons riding over a bumpy landscape, which is what they encounter in the 2DEG. The electrons have more than enough energy to ride over any bump in the landscape, and the concentrations of electron flow seen here are unexpected indirect effects of that bumpy ride. The channeling or branching was a surprise and has serious implications for small electronic devices of the future.

"Transport VI" is an excellent example of the wonderful way nature emulates herself in different contexts. Thus, the folding of the electron trajectories is like looking through translucent kelp, or like ridges on a mountain.

Heller's work was included in the exhibit "Approaching Chaos," shown at the National Science Foundation (NSF) headquarters in Arlington, Va., July thru October 2002, as part of "The Art of Science Project." The Art of Science Project was conceived and implemented by a cross-directorate committee of NSF staff. Its purpose is to bring to NSF, original works of art that visually explore the connections between artistic and scientific expression.
