Symposium EL03-Emerging Ionic Semiconductors—Research and Applications

Semiconductor technology today relies on group-IV, III-V, and II-VI materials that feature four-fold coordination and covalent sp3 bonding. The remarkable emergence of halide perovskite semiconductors has raised the prospects of materials with ionic bonding and more complex crystals structures for optoelectronic applications, including photovoltaics and solid state lighting. Balancing ionic and covalent bonding in complex structure motifs creates opportunities to discover semiconductors with properties and processing pathways unattainable in conventional materials. Examples of such include complex oxide materials designed to combine ferroelectricity with band gap in the VIS-NIR, and chalcogenide perovskite semiconductors that feature excellent light absorption and environmental stability. This symposium will be a forum to report exciting progress in these emerging ionic semiconductors, focusing on complex chalcogenides and oxides but also including nitrides and related compounds as appropriate. We encourage reports from a wide range of activities including theory, materials synthesis and characterization, devices, and applications. Abstracts on halides, binary oxides, and other conventional III-V and II-VI semiconductors are discouraged.

Topics will include:

  • Computational and machine learning-enabled materials design
  • Synthesis and processing science, bulk materials and thin films
  • Physics and chemistry of complex-structured semiconductors
  • Advanced characterization, with focus on device-relevant properties
  • Device fabrication and test
  • Applications, including but not limited to solar energy conversion, solid state lighting, microelectronics, thermoelectrics and phase change materials
