Organic semiconductors enable many technologically important applications such as organic light emitting diodes, solar cells and flexible circuits due to their unique physical properties and chemical structure tunability. Conventional amorphous organic semiconductors show low carrier mobility as their charge transport is limited by their structural order. Therefore, charge transport in organic semiconductors can generally be improved by higher degree of structural order and crystallinity. In this presentation, we will show efficient conversion of vacuum processed amorphous thin films to single crystalline thin films through annealing with appropriate surface treatment. We will also show functional devices such as field-effect transistors and light emitting diodes built on the single crystalline thin films and discuss their potential for high performance circuit and optoelectronics applications.
