Harvard University physicist Eric J. Heller, inspired by the images coming from the laboratory of his colleague Robert M. Westervelt, has created a series of interpretations based on the flow of what's called a two-dimensional electron gas, seen in this branching pattern named Transport VI. These gases are found in certain semiconductor devices, such as high electron-mobility transistors, that have a thin buried layer different from the rest of the structure.
