Experimental study demonstrates chemoresponsive field-effect transistors using self-assembled hydrocarbon monolayers, indicating potential for ultra-sensitive nanoscale molecular sensors.

Key Points

Fabricate functional field-effect transistors from monolayers of polycyclic aromatic hydrocarbons capable of detecting and responding to chemical targets in their environment.
Functionalized polycyclic aromatic hydrocarbons were assembled into columnar monolayers anchored to silicon oxide surfaces.
Ultrasmall source and drain electrodes separated by a few nanometers were engineered by oxidatively cutting individual metallic single-walled carbon nanotubes.
Molecular columns bridging the nanotube gap produced transistors exhibiting high gate efficiency and large current modulation.
Transistor electrical properties shifted significantly upon exposure to the electron-deficient chemical tetracyanoquinodimethane (TCNQ).
