Organic electronics are widely believed to be the most viable platform to manufacture pervasive and disposable electronics on flexible substrates cheaply and with a lesser environmental impact than conventional electronics. The performance of organic electronic devices is closely tied to the packing structure, morphology and interfaces in organic semiconductor thin films, which in turn are intricately linked to molecular processes operant during their assembly. Typically, vacuum sublimation/evaporation is used to fabricate ordered molecular films. While the simplicity of thermal deposition processes makes them attractive, they provide few knobs in way of process control. Supersonic molecular beams have emerged as a way to tailor the assembly of complex molecular building blocks by manipulating the state of incident molecules (e.g., kinetic energy, vibro-rotational states, molecular clustering). Our research shows that tunable supersonic molecular beams can tailor the growth behavior, morphology, and packing structure of organic small-molecule semiconductors in unprecedented ways. These changes often affect the field effect mobility of organic semiconductors and offer a pathway to controlling the performance of organic electronic materials. Our findings indicate that molecular-scale control of interfaces and thin films is achievable; it is contingent upon the development of adequate processing strategies.
