With Organic Electronics Rapidly Maturing, Interest in Energetics of Molecular Interfaces

molecular electronics growing, and prospects of single-molecule electronics improving, there is an increasing need to understand the interactions and electronic structure at interfaces between molecular and nonmolecular phases1-3. The level of activity in new materials for organic light-emitting diodes, organic field-effect transistors, and organic solar cells; optical or transport characterization of organic thin films; and fabrication of other organic electronic devices has risen dramatically over the past decade46. This work has demonstrated that interfaces play a critical role because they determine, to a large extent, the properties and performance of materials and devices. Interfaces become even more important as device dimensions decrease in nanoelectronics and single-molecule electronics.
