Tunable molecular orientation and elevated thermal stability of vapor-deposited organic semiconductors.

Shakeel S Dalal et al.

Proceedings of the National Academy of Sciences of the United States of America, 112(14), 4227-4232 (2015-04-02)

Physical vapor deposition is commonly used to prepare organic glasses that serve as the active layers in light-emitting diodes, photovoltaics, and other devices. Recent work has shown that orienting the molecules in such organic semiconductors can significantly enhance device performance.
