Deformable Organic Nanowire Field‐Effect Transistors

Advanced Materials, 2018
AbstractDeformable electronic devices that are impervious to mechanical influence when mounted on surfaces of dynamically changing soft matters have great potential for next‐generation implantable bioelectronic devices. Here, deformable field‐effect transistors (FETs) composed of single organic nanowires (NWs) as the semiconductor are presented.

Single crystal field-effect transistors based on an organic selenium-containing semiconductor

, 2004
We report on the fabrication and characterization of single crystal field-effect transistors (FETs) based on diphenylbenzo diselenophene (DPh-BDSe). These organic field-effect transistors (OFETs) function as p-channel accumulation-mode devices.

Electron-phonon and electron-electron interactions in organic field effect transistors [PDF]

, 2007
Recent experiments have demonstrated that the performances of organic FETs strongly depend on the dielectric properties of the gate insulator. In particular, it has been shown that the temperature dependence of the mobility evolves from a metallic-like ...
