Summary: A new doping system using an organic salt p-dopant is reported to significantly improve the device performance of organic field-effect transistors (OFETs). The optimized doping ratios increase the hole mobility and reduce the threshold voltage, while also reducing contact resistance and activation energy. The study also explores the impact of doping ratios on trap density.

Summary: Monolayer molecular crystals (MMCs) have aroused global research interest due to their unique properties. Compared with their bulk counterparts, MMCs have lower contact resistance, making them ideal carriers for studying the intrinsic properties of organic semiconductors. However, studies on anisotropic charge transport in MMCs are still rare. In this study, by non-destructively preparing electrodes on MMCs, anisotropic charge transport properties of two typical MMCs were obtained, providing a basis for realizing high performance device arrays with low device-to-device variation.

Summary: 2D organic semiconductor single crystals have the potential to be used in ultrathin, flexible, and transparent field-effect devices. However, the light emissive properties of these crystals have not been reported, and achieving both high charge-carrier mobility and bright luminescence in one material is still a challenge. In this study, a high-mobility 2D organic semiconductor based on a BTBT-derivative is presented, which demonstrates both high charge-carrier mobility and prominent light emissive properties.

Summary: In this study, high-mobility stretchable semiconducting blend films were prepared by blending a polymer semiconductor with an elastomer. The resulting blend films have low crystallinity and high aggregation degree, resulting in high stretchability and high mobility. The fully stretchable organic transistors exhibit high hole maximum mobilities at various strains and show high mechanical robustness during repeated stretching-releasing cycles.

Summary: In this study, robust pi-conjugated radical cations were obtained from the oxidation of hexabenzoperylene (HBP) derivatives. The radical cation of HBP-B was successfully crystallized and exhibited high conductivity. Additionally, the formation of radical cation in the solid state was observed for HBP-H. This allowed the organic field effect transistor of HBPH to function as a nonvolatile optoelectronic memory with high memory switching contrast and long-term stability.
