The role and purpose of this work is to investigate a new vertical transistor structure that does not require the use of lithography and can be fabricated in ambient conditions using solution processed active layers. Towards this, planar transistor structures are studied featuring organic semiconducting active layers. Solution processed films are seen to produce devices with comparable or improved device behaviour in comparison to physically deposited active layers. Showing solution processed devices are capable of producing/being used in high performance field effect devices. However, inherent shortcomings in planar structures such as parasitic contact resistances and device scaling due to lithographic resolutions ultimately limit the performance of planar devices. Providing motivation to develop a novel vertical transistor structure that features dimensions controlled by the thickness of a solution processed film and large operational areas, in an effort to improve the prospects of organic transistor devices.
