From: On Practical Charge Injection at the Metal/Organic Semiconductor Interface
Plots of (a) transfer characteristics in the saturation region of pentacene OFETs with gold, copper and aluminium charge injection interlayers and (b) contact resistance against work function for 11 different contact metals used as charge injection interlayers.It is noted that the change of shadow mask for metal evaporation and transfer to chamber for electrical characteristic were done under atmosphere, defined as ex-situ condition. Also, plots of (c) transfer characteristics with gold, copper and aluminium, which was processed and characterised under nitrogen and (d) contact resistance against work function for 5 different contact metals under in-situ condition. The bar in orange color in (b) is used for a guide to eyes.
