文摘

We report a field configurable transistor (FCT) fabricated on a Si nanowire FET platform by integrating a thin film of conjugated polymer poly[2-methoxy-5-(2′-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) and an ionic conductive layer (RbAg₄I₅) into the gate. The FCT can be precisely configured to desired nonvolatile analog state dynamically, repeatedly, and reversibly by controlling the concentration of iodide ions in the MEH-PPV layer with a gate voltage. The flexible configurability and plasticity of the FCT could facilitate field-programmable circuits for defect-tolerance and synapse-like devices for learning.
