Different Work Regimes of an Organic Thin Film Transistor OTFT and Possible Applications in Bioelectronics [PDF]

American Journal of Bioscience and Bioengineering, 2015
This paper presents an organic semiconductor transistor, with a vertical current modulation and a horizontal conduction. The simulations show a stronger top gate influence and establish four work regimes, depending on the top and bottom gates biasing. In the most favorable regime for the holes channel, under the reverse biased n+p junction, the holes ...
