title: Unwrapping core-shell nanowires into nanoribbon-based superstructures.
abstract: A prize for the ribbons: High-quality crystalline semiconducting nanoribbons can be prepared by "unwrapping" core-shell nanowire precursors. For example, Ge nanowires were coated with a Si shell and the top surface was carved by etching whereas the sides were protected by a thin layer of photoresist material. Finally the Ge core was removed selectively by chemical means to give fully opened and flat nanoribbon structures.
