High performance pentacene organic field-effect transistors consisting of biocompatible PMMA/silk fibroin bilayer dielectric
Pentacene organic field-effect transistors （OFETs） based on single- or double-layer biocompatible dielectrics of poly（methyl methacrylate） （PMMA） and/or silk fibroin （SF） are fabricated. Compared with those devices based on sin- gle PMMA or SF dielectric or SF/PMMA bilayer dielectric, the OFETs with...

| description | Pentacene organic field-effect transistors （OFETs） based on single- or double-layer biocompatible dielectrics of poly（methyl methacrylate） （PMMA） and/or silk fibroin （SF） are fabricated. Compared with those devices based on sin- gle PMMA or SF dielectric or SF/PMMA bilayer dielectric, the OFETs with biocompatible PMMA/SF bilayer dielectric exhibit optimal performance with a high field-effect mobility of 0.21 cm2/Vs and a current on/off ratio of 1.5 × 104. By investigating the surface morphology of the pentacene active layer through atom force microscopy and analyzing the elec- trical properties, the performance enhancement is mainly attributed to the crystallization improvement of the pentacene and the smaller interface trap density at the dielectric/organic interface. Meanwhile, a low contact resistance also indicates that a good electrode/organic contact is formed, thereby assisting the performance improvement of the OFET. |
