Description

This etch-a-sketch style picture was created during a growth of GaSb by molecular beam epitaxy. It is the result of a random walk pattern taken by excessive metallic Ga droplets on the surface during growth, due to Sb deficiency. I think it looks like a robot looking at a person with lots of hair, but other people have seen different images, which is why I believe the artistic interpretation of this picture is so great. Hope that you like it!
