Symposium EP5—Metal Oxide Hetero-Interfaces in Hybrid Electronic Platforms

Metal oxides interfaced with organic, inorganic, metal, or dissimilar metal oxide thin films and semiconductors are increasingly considered one of the most viable solutions for the large-scale development and deployment of entirely solution-processed hybrid electronic platforms. The grand challenge is that surface energetics and functionalities are often distinct from bulk properties and are expected to have direct impact on thin film hybrid electronic systems, where the interfaces are the devices. A fundamental understanding of metal oxide surfaces and complex processes occurring at such hetero-interfaces is central to implementation of novel material combinations and new devices architectures to advance the field of hybrid electronics – specifically to elucidate interfacial chemistry, local structure and composition, structural reorganization and interfacial charge transport for device relevant materials in-operando.

The emphasis of this symposium is not solely on device performance, which is adequately covered in numerous other symposia, but on innovative characterization strategies and new interfacial phenomena at buried interfaces. Research focusing on scientific and technical challenges currently encountered with novel materials and processing techniques being implemented in a range of technologies are encouraged, including but not limited to: batteries; supercapacitors; solar fuels; photovoltaics and solid-state lighting. This symposium will aim to emphasize correlating measured rates of charge transfer and/or transport with interfacial structure and electronic properties that are divergent from bulk. The metal oxide interfacial issues concerning opto-electronic properties of thin film semiconductors are appropriate, with planned sub-sections on metal oxide/organic, metal oxide/inorganic (including quantum structures and perovskites), metal oxide/metal oxide, and metal oxide/metal, again with the emphasis on how atomic structure translates into macroscale behaviors. Work detailing the characterization and control of surface defects at metal oxide/liquid heterojunctions for solar fuels and battery applications is also within the scope of the symposium. Particular consideration will be given to contributions in which a combination of optical, spectroscopic and electronic methods provide evidence for need/importance of more fundamental understanding regarding the role of surfaces and interfaces in determining functionality across length scales, in the broader context of materials for energy technologies.

Topics will include:

  • Composition and electronic structure at buried interfaces.
  • Novel techniques for in-situ growth and in-operando device interface characterization.
  • Correlation of atomic interfacial structure with macroscopic properties.
  • Heterogeneity of nanostructured interfaces – 2D and 3D architectures.
  • Lifetime evolution of interfacial and near interfacial structure and composition.
  • Surface structure and electronic properties of solution vs. vacuum processed materials.
  • Large scale manufacturing – rapid optical and electronic characterization.
