This paper demonstrates a simple and promising approach for
enhancement of eld effect device characteristics in solution
processible organic semiconductors. A nonpercolating network
of random dispersed intrinsic silicon nanowires was incorporated
into a semiconducting polythiophene polymer, forming a dual layer
structure for the nanocomposite FETs. Measurement results of p
type Si nanowireP3HT nanocomposite transistors show notable
enhancement with respect to device mobility, threshold voltage,
hysteresis and air stability, over that of FETs with pristine P3HT. This
work furthers our understanding of the interaction between poly
thiophene polymers and nonpercolating silicon nanowires, where
