Large-area, selective transfer of microstructured silicon: A printing-based approach to high-performance thin-film transistors supported on flexible substrates

The selective transfer and accurate registration of microstructured silicon (mu s-Si) across large areas is demonstrated using a printing-based procedure applicable to both rigid (i.e., glass) and flexible plastic substrates (see Figure). The utility of this technique to construct macroelectronic systems that incorporate high-performance mu s-Si thin-film transistors on flexible substrates is also demonstrated.
