| Abstract | |
We report the first low voltage organic P3HT transistor over glass substrates and titanium oxynitride (TiOxNy) deposited by reactive r.f. magnetron sputtering. The transistor operating voltage was -3V with a maximum current of 1.11 mu A. Charger carrier mobility (mu) was 0.01 cm(2)/Vs, threshold voltage (V-t) -0.5 V, on-off current ratio (I-ON/OFF) 200 and subthreshold swing (S) 0.75 V/decade. We also present a study of the dielectric constant (k) of organic insulator PMMA in several processing conditions. ITO/PMMA/Au capacitors provided a dielectric constant of ca. 3.5, which is very similar to SiO2 performance. (AU) | |
