Degradation of pentacene deposited on gold, aluminum and parylene surfaces: Impact of pentacene thickness

► Forward current degradation in Schottky diodes from oxygen in the pentacene films ► Reverse current degradation from oxygen diffusion to bottom aluminum contact ► Degradation of pentacene diodes related to oxygen interaction with bottom contact ► Thicker pentacene films are more stable due to reduced oxygen at the bottom contact ► Proper pentacene thickness is important to reduce degradation of Schottky diodes
