The American Association for Crystal Growth (AACG) would like to thank the IUCr for its support of the 19th International Conference on Crystal Growth and Epitaxy (ICCGE-19). The conference was held from 28 July to 2 August 2019 in beautiful Keystone, CO, USA, under the auspices of the International Organization for Crystal Growth (IOCG) jointly with the 19th US Biennial Workshop on Organometallic Vapor Phase Epitaxy (OMVPE-19) and, as is traditional, was preceded by the 17th International Summer School on Crystal Growth (ISSCG-17), held at the YMCA of the Rockies in nearby Granby, CO.

ICCGE-19 was the latest in a sequence that started with ICCG-1 in Boston, MA, USA, in 1966, which marked the formation of the crystal growth community as an independent discipline. The key principle of the IOCG and the ICCGE conferences is that the theory and practice of crystal growth are common across a range of materials and applications and that we have much to share with one another. The year 2019 also marked the 50th anniversary of the founding of the American Association for Crystal Growth.

The OMVPE-19 workshop continued a tradition, started at Cornell University, Ithaca, NY, USA, in 1983, of bringing together specialists in the OMVPE field from industry, academia and government laboratories. The informal atmosphere and scenic surroundings of the workshop provided a venue for the presentation of new results and for newcomers to the field to familiarize themselves with OMVPE science and technology.

Overall there were 639 attendees from 31 countries, including 50% from the US, 20% from Europe, 19% from Japan and 4.5% from China.

A total of five IUCr Young Scientist subsistence and travel awards were made to graduate students. The recipients and the presentations they gave were as follows:

  • Scott Dossa (University of Minnesota, Minneapolis, MN, USA) “Modeling the Optical Floating Zone Crystal Growth System for Materials Discovery” (Invited)
  • Michael Liao (UCLA, USA) “Surface Evolution of Single Crystalline β-Ga2O3 with Chemical Mechanical Polishing and Annealing at an Elevated Temperature”
  • Grace Pan (Harvard University, Cambridge, MA, USA) “Effective Dimensionality-Tuned Electronic States in Metastable Nickel Oxide Thin Films”
  • John Roerig (University of Minnesota, Minneapolis, MN, USA) “Evaluation of an Inverted Vertical Gradient Freeze Method for Cadmium Zinc Telluride”
  • Xiaotian Zhang (Penn State, PA, USA) “Epitaxial Growth of Layered β-In2Se3 Thin Films Via Metalorganic Chemical Vapor Deposition”

The IUCr also gave awards to two student poster presenters:

  • Smail Amari (CEA LITEN LCO, Grenoble, France), “Crystal Growth and Characterization of CH3NH3PbBr3 Single-Crystals for X-Ray Photodetection”
  • Muad Saleh (Washington State University, Pullman, WA, USA) “Electrical and Optical Properties of Zr Doped β-Ga2O3 Single Crystals Grown by Czochralski Method”

ICCGE/OMVPE-19 provided sessions for presentation and discussion of recent advances in research and development over all aspects of crystal growth, epitaxy, characterization and applications. A total of 473 oral presentations and 75 poster presentations were delivered. The conference was an excellent opportunity to advance the science and technology of crystal growth, epitaxy, characterization and applications, as well as to convene with old and new friends, colleagues and business associates.

The following plenary talks were given in the Monday, Tuesday and Thursday Plenary Sessions:

  • Robert Feigelson (Stanford University, CA, USA) “A Retrospective on the American Association for Crystal Growth on Its 50th Anniversary”
  • Thierry Duffar (SIMaP-EPM, Grenoble, France) “Defect Engineering in Bulk Crystal Growth”
  • Darrell Schlom (Cornell University, Ithaca, NY, USA) and Reinhard Uecker [Leibniz Institute for Crystal Growth (IKZ), Berlin, Germany] “Development of New Perovskite Substrates Enabling Strain Engineering of Oxide Thin Films” (IOCG Frank Prize talk).
  • Kazuo Nakajima (Tohoku University, Japan, emeritus) “Development of High-Quality Crystals for III-V Quaternary Optical Semiconductors and Solar Cell Silicon and Their Industrial Applications” (IOCG Laudise Prize talk).
  • Anton Jesche (Center for Electronic Correlations and Magnetism, Institut für Physik, Universität Augsburg, Germany) “The Metal Flux as a Powerful Tool for the Solid State Physicist” (IOCG Schieber Prize talk).
  • Kei May Lau (Hong Kong University of Science and Technology) “Advantages and Challenges of Growing III-V Photonic and Electronic Devices on Si”
  • Jim De Yoreo (Pacific Northwest National Laboratory, Richland, WA, USA) “They Call It Free Energy So, Hey, Why Pay?”

Once again, we would like to express our appreciation for the IUCr’s support. There is great synergy between our communities, and crystallographers were well represented. In particular we thank Hanna Dabkowska and Andrea Zappettini for their support and attendance. Hanna is the new IOCG Vice President and Andrea will be the co-chair of ICCGE-20 in Naples, Italy, in 2022.
