Description: 
We studied environmental stability of top contact pentacene TFTs with active layer evaporated at different growth rates. We measured the transfer characteristics in vacuum and in air and after storing the devices in oxygen for several days. Different pentacene growth rates result in different grain size of active layer. This morphology difference influences the hysteresis of transfer characteristics induced by water absorption. On the contrary, aging effects on the transfer characteristics of pentacene O-TFTs, induced by oxygen diffusion into the active layer, are not related to structural characteristics of pentacene film.
