Dendrite Electrons injected at the top of the image rain down in the branched flow pattern seen, as they ride over a bumpy landscape These images render electron flow paths in a"two dimensional electron gas". Inspired by the experiments of Mark Topin ka, Brian Leroy, and prof. Robert Westervelt at Harvard. Theory performed by Scot Shaw These two images are based on the actual electron flow patterns for electrons riding over bumpy landscape. The electrons have more than enough energy to ride over any bump in the landscape, and the concentrations of electron flow(white/pink in Dendrite, and darkest streaks in Transport lID are newly discovered indirect effects of that bumpy ride. The channeling ol branching was unexpected and has serious implications for small electronic devices of the future. The electron flow images are excellent examples of the wonderful way nature emulates herself in different contexts. Thus, the folding of the electron trajectories looks like looking through translucent kelp! Or, like ridges on a mountain

End of coherence Electron flow launched from the upper center in a weakly random potential, showing quantum phase as color, and the decay of the coherence of the phase to the lower right. Electron flow launched from the upper left in a weakly random potential is colored according to quantum phase Trajectories were written by color addition, so that color saturation represents coherence of the trajectories. they get farther from the source they loose coherence with each other. The color banding diminishes. A data subtraction was done using saturation as the marker, aving the least coherent region in the lower right transparent and showing the artificial color gradient beneath

" Inspired by the experiments of Mark Topinka, Brian Leroy, and Prof. Robert Westervelt at Harvard.

Nanowire Electron paths in a nanowire, including imperfections in the wire. o. As components of electronic devices get ever smaller, wires connecting those components must also shrink in oportion. At the micron to nanometer scale, where devices are now being built, the wave nature of matter is becoming critical. This may be an advantage or it may be a problem. Making and understanding nanowires is certainly a challenge. Real nanowires have imperfections. The image Nanowire grew out of a study of electron flow in a wire riddled with random imperfections. It shows electrons injected at one point contact, the"sun flowing out from there to all regions of the wire. The disturbance of the electron tracks by the imperfections is shown in their somewhat unruly paths. The quantum aspect of the electrons is shown in color: we can follow the wave nature of the electrons by assigning yellow to the crest of the wave, blue to a trough, continuously around the color circle. The creative process leading to Naonwire is typical of my artwork: a synthesis of research and artistic creation, each one enhancing the other Experiments conducted by M. Topinka, B LeRoy and B Westervelt measuring electron transport in semiconductor microstructures led to scientific illustrations of electrons riding over bumpy landscape potentials. Experimentation with various methods of recording individual electron tracks(overwrite, transparency, color combination) led to a variety of effects and expanded the horizon of the medium. The resulting Transport series is the first of large format hig h resolution electron flow images using branched flow physics. These images revealed the caustics formed when electrons flow from a particular point over a hilly landscape
