Pre-synaptic DC bias controls the plasticity and dynamics of three-terminal neuromorphic electrolyte-gated organic transistors

Electrolyte-Gated Organic Thin-Film Transistors

There has been a remarkable progress in the development of organic electronic materials since the discovery of conducting polymers more than three decades ago. Many of these materials can be processed from solution, in the form as inks. This allows for using traditional high-volume printing techniques for manufacturing of organic electronic devices on various flexible surfaces at low cost. Many...

Characterization and simulation of electrolyte-gated organic field-effect transistors.

In this work we fabricate and characterize field-effect transistors based on the solution-processable semiconducting polymer poly(3-hexylthiophene) (P3HT). Applying two independent gate potentials to the electrolyte-gated organic field-effect transistor (EGOFET), by using a conventional SiO(2) layer as the back-gate dielectric and the electrolyte-gate as the top-gate, allows the measurement of ...

Transient analysis of electrolyte-gated organic field effect transistors

A terminal charge and capacitance model is developed for transient behavior simulation of electrolyte-gated organic field effect transistors (EGOFETs). Based on the Ward-Dutton partition scheme, the charge and capacitance model is derived from our drain current model reported previously. The transient drain current is expressed as the sum of the initial drain current and the charging current, w...

Phospholipid film in electrolyte-gated organic field-effect transistors

A totally innovative electrolyte-gated field effect transistor, embedding a phospholipid film at the interface between the organic semiconductor and the gating solution, is described. The electronic properties of OFETs including a phospholipid film are studied in both pure water and in an electrolyte solution and compared to those of an OFET with the organic semiconductor directly in contact wi...
