A threshold voltage shift of up to 1.2 V was observed with 1%-2% chromophore coverage.

The observed conductance changes were reversible and repeatable.

Conclusions:

The hybrid material exhibits light-responsive conductivity modulation.
Chromophore-functionalized nanotubes show promise for integrated nanophotodetector applications.
