Comparison of the Mobility–Carrier Density Relation in Polymer and Single‐Crystal Organic Transistors Employing Vacuum and Liquid Gate Dielectrics

The mobility of polymer and single-crystal transistors using a universal test-bed where the injected carrier density can vary more than four orders of magnitude are investigated and compared. A striking difference in the mobility–carrier density relationship was observed, revealing a fundamentally different charge-transport mechanism between polymer and single-crystal transistors.
