A selective contact‐doping technique based on solid‐state diffusion is developed by Keehoon Kang, Takhee Lee, and co‐workers in article 1806697 for enhancing carrier injection in organic field‐effect transistors. The dopant molecules become structurally implanted in well‐defined regions of the polymer film near the contact electrodes. This new strategy of contact doping achieves a markedly improved...
Organic semiconductors (OSCs) have been widely studied due to their merits such as mechanical flexibility, solution processability, and large‐area fabrication. However, OSC devices still have to overcome contact resistance issues for better performances. Because of the Schottky contact at the metal–OSC interfaces, a non‐ideal transfer curve feature often appears in the low‐drain voltage region. To...
