Transfer printing for deterministic assembly of nanomembranes formed by lithographic processing of a wafer substrate. (a) Schematic illustration of selective retrieval (top) and printing (bottom) of nanomembranes using a stamp. Grey, red, blue and yellowish green color represent inorganic nanomaterial, adhesive, stamp and receiving substrate, respectively. (b) An image of an automated printer that consists of a programmable, three axis translation stage, a stamp fixture, a high resolution microscope and integrated load cells. (c) GaAs nanomembranes printed in a sparse array on a plastic sheet, subsequently bent around a glass cylinder (top). (d) Magnified view of printed GaAs nanomembranes derived from different layers of epitaxial growth (bottom). Reprinted with permission from Yoon et al.45 Copyright 2010 Nature Publishing Group.
