Threshold Voltage Modulation of Polymer Transistors by Photo-induced Charge-Transfer between Donor-Acceptor Dyad |
| 초록 |
In this work, we have studied photo-induced optoelectronic properties of conjugated polymers from device characterization and quantum calculation on the polymers. It was demonstrated that the photo-sensitive conjugated polymer with electron donor-acceptor dyads can modulate charge accumulation by photo-irradiation resulting in threshold voltage shift in the polymer field-effect transistors (PFETs) while this effect of the photo-inactive polymer is relatively low. These results suggest that the feasible molecular design strategies can provide an effective platform to achieve controllable threshold voltage modulation in PFETs. |
