Thin Oxide Film (IMAGE) DOE/Argonne National Laboratory Caption Argonne physicist Jeff Eastman holds a thin oxide film which dramatically increases its conductivity when a small current is applied. The discovery could be useful in studies for better electronics or catalysts. Credit Photo by Mark Lopez/Argonne National Laboratory.
