- Creating nanotube networks in no time Hexagonal networks of nanotubes appear when enough copper atoms penetrate the surface layers of a vanadium selenide crystal. Researchers at DOE's National Center for Electron Microscopy at Lawrence Berkeley National Laboratory and the University of Kiel have found a new way to form complex networks of nanotubes on the surface of vanadium selenide, a layered crystal. Copper atoms infiltrate the crystal for several minutes in high vacuum. Then hexagonal networks of tubes, intricately branched and connected, form in less than a second. The copper initiates a phase change in the topmost layers, which expand and glide over the underlying layers. A network of prismatic folds results, having the cross section of a pitched roof four nanometers high.
