Oxide based electronics are seeing a broad set of applications based on new materials and the ability to tailor structure and functionality to enable new functionality. This includes improved TCs including hybrid nanowire TCOs as well as  new semiconductors for high speed and wide bandgap electronics, new piezoelectric materials and photovoltaic absorbers. Achieving this requires an increasingly broad materials set but also structural diversity from amorphous to expitaxial and the inclusion of new hybrid materials. Critical in the development of oxide electronics and flexible oxide electronics are not only new materials but also a new level of interfacial control to enhance the control of specific charge transport across interfaces. There is also an increasing potential of the integration of ferroelectric or polar character to the materials and interfaces. Increasingly diverse structures with complex compositions and gradients as well as amorphous and crystalline metal oxide materials as well as wide band-gap nonoxide materials including e.g. nanowire networks and quantum dot structures are extending device designer’s palette of transparent conductors and semiconductors by addressing a variety of cutting edge applications in flexible electronics, new active optoelectronics, even spin photonics. New advanced in materials and processing are also extending the range of the more experienced use of transparent conducting oxides in large area flat-panel displays, thin-film solar cells, antistatic coatings, functional and smart glasses and a number of other applications.
Underlying the development of new functional materials for example organic and nanotube based TCs is the need for a clearer and predictive understanding of basic materials science such as the electronic structure, carrier and trap origin, mobility and scattering, and doping mechanisms which govern conductivity and transparency, coupled with a better insight into interfacial and chemical compatibility issues and the development of models of the performance limits of materials and devices.
Objective of the International Symposium “Development and Application of new Functional Transparent Conducting and Semiconducting Oxides”, which follows the discussions on related subjects held at previous CIMTEC Conferences, is to gather specialists from academia and industry to highlight updated developments in the area from fundamental science to materials synthesis, processing techniques device development and advanced/novel/prospective applications.
