Welcome to ICDS-30

The 30th International Conference on Defects in Semiconductors will be held in Seattle, Washington from July 21 to July 26, 2019.

The conference promotes a fundamental understanding of point and extended defects in semiconductors, including electrical, vibrational, optical, and magnetic phenomena. Held in vibrant downtown Seattle, ICDS-30 will facilitate stimulating discussions on defects in materials for micro- and optoelectronics, quantum computing, photovoltaics, and other applications. Unique among international conferences, ICDS covers a range of materials, with defects as the central organizing principle. This approach is extremely fruitful for advancing knowledge of emerging materials such as wide-band-gap semiconductors, doped nanoparticles, and 2D materials, as well as exciting developments in “old” materials such as silicon.


Topics include experimental and theoretical research in the following areas:

  • Point and line defects in bulk crystals, thin films, nanocrystals, and 2D materials
  • Defect-induced optical, electronic, magnetic, and vibrational properties
  • Single-defect phenomena
  • Advances in characterization, computational methods, growth, and processing
  • Spectroscopy of defect centers
  • Diffusion, thermal transport, and isotope effects
  • Applications to devices such as light-emitting diodes and solar cells
  • Nanotechnology and materials science of functional defects

A broad range of materials will be discussed, including:

  • Group-IV semiconductors and their alloys
  • III-V and II-VI compound semiconductors
  • Oxide and nitride semiconductors
  • Organic semiconductors and graphene-based materials
  • Topological insulators
