Figure 1: Comparison of output characteristics of   OTFTs with two different insulators, BZN (right) and BZN with a parylene   surface treatment (left). VGS is stepped from 5 V to -5 V for both   devices. Typical VT for BZN is ~2V. Treating the surface of the   BZN with parylene shifts the V­T to ~-0.5 V.
