Amir N. Hanna, et al., "Wavy Channel TFT-Based Digital Circuits." IEEE Transactions on Electron Devices 63 (4), 2016, 1550. Abstract: We report a wavy channel (WC) architecture thin-film transistor-based digital circuitry using ZnO as a channel material. The novel architecture allows for extending device width by integrating vertical finlike substrate corrugations giving rise to 50% larger device width, without occupying extra chip area. The enhancement in the output drive current is 100%, when compared with conventional planar architecture for devices occupying the same chip area. The current
