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 (μs-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 μs-Si thin-film transistors on flexible substrates is also demonstrated.
