(Received 14 May 2010; accepted 14 June 2010; published online 9 July 2010)

Precise control over the threshold voltage of pentacene-based organic thin film transistors was achieved by inserting a genetically engineered quartz-binding polypeptide at the semiconductor-dielectric interface. A 30 V range was accessed with the same peptide by adjusting the pH of the solution for peptide assembly while leaving other device properties unaffected. Mobility of 0.1–0.2 cm2 V−1 s−1 and on/off current ratio of >106 could be achieved for all devices regardless of the presence of the neutral peptide or the peptide assembled in acidic or basic conditions. This shift in threshold voltages is explained by the generation of charged species and dipoles due to variation in assembling conditions. Controlling device characteristics such as threshold voltage is essential for integration of transistors into electronic circuits.

FIG.3
Threshold voltage vs assembling pH for QBP-modified thin film transistors. The horizontal line represents the mean threshold voltage for a nonpeptide modified transistor. The vertical lines represent critical pHs in acidic and basic conditions, respectively. Dashed lines represent equivalence points for the titration of peptide with acid (pH = 4.2) or base (pH = 9.9). Dotted lines represent the pKas of the C-terminus (pKa = 2.9), N-terminus (pKa = 6.9), and phenol side chain on tyrosine (pKa = 13.4).
