Nanomembranes: Single Crystal Gallium Nitride Nanomembrane Photoconductor and Field Effect Transistor (Adv. Funct. Mater. 41/2014)

Using a special electrochemical procedure, J. Han and colleagues succeed in slicing off Gallium nitride from a thick and rigid structure into a form of nanomembrane (NM) with a thickness of only hundreds of atomic layers. The NMs presented on page 6503 possess a very favorable transport property, while its two surfaces (top and bottom) present both opportunities and challenges for new applications.
