==Summary==
The purpose of this study was to investigate a different fabrication technique for creating single crystals of pentacene to be used for organic field effect transistors.  The liquid-phase crystallization process creates single crystals by evaporating off a solvent when pentacene is in solution.  The pentacene crystals formed by this method then had their semiconducting properties measured and these properties were compared to pentacene crystals grown using different methods.

Organic field effect transistors (OFETs) have many favorable properties over current field effect transistors (FETs).  The most popular OFET, due to its optimal electronic properties is pentacene.
