“…In fact, several works are currently being published on ever increasing hole mobility [1]- [6] with values equaling or exceeding those of amorphous silicon TFTs, at a fraction of their cost. Indeed, one of the main advantages of OTFT with respect to their inorganic counterpart, is the availability of very inexpensive production processes, such as spin-coating, etc [6]- [9], mainly due to the very low temperature required for the organic semiconductor deposition, compared to those of a-Si-TFT. Another advantage is the compatibility of organic semiconductors with plastic materials, which are lighter, more robust and much less expensive than glass.…”
