Resumen:

In this paper we show that the mobility reduces for OTFTs with similar channel length when the channel width is increased. The effect is shown in staggered bottom contact organic thin film transitors (OTFTs) made of the P-Type semiconductor Poly(Triarylamine) PTAA and Cytop® as insulator. It can also be seen from experiment, that this mobility reduction is associated to an increase in the density of localized traps present in the active layer material. An interpretation of this effect is presented. © 2012 IEEE.
