Organic electronics have attracted intensive research interest in the past decades Yao et al., 2020;Tang 2021). The ever-increasing demand for organic calls development of high-performance and high-stability thin-film transistors (OFETs). OFETs are considered key components to fabricate flexible printable devices promising applications, such as displays, chemical sensors, wearable devices, radi...

Unidirectional dewetting enables the production of large-area thin films with high efficiency at low cost. Herein, we report homogeneous unidirectional dewetting on large-area microdroplet arrays via gravity-induced deformation in droplets combined with alternating lyophilic/lyophobic patterns. This process allows the scaled-up deposition of thin films, including organic semiconductors and tran...

Soft, conformable electrical contacts provide efficient, noninvasive probes for the transport properties of chemically and mechanically fragile, ultrathin organic semiconducting films. When combined with high-resolution printing and lamination techniques, these soft contacts also form the basis of a powerful technique for fabricating flexible plastic circuits. In this approach, a thin elastomer...

To demonstrate first aspect, voltage-amplifying organic tran...

Organic and polymeric semiconductor-based thin-film fieldeffect transistors (OFETs) are of great interest for low-cost largearea memories and driving circuits in display applications.1 In these organic devices, the charge carrier transport is dominated by the hopping mechanism at room temperature.2 Therefore, highly ordered thin films with large interconnected polycrystalline grains are necessa...
