9th International Workshop on Crystal Growth Technology (IWCGT-9)
Berlin/Germany · June 8–11, 2026
Crystal growth is continuing to shape the foundation of major advances in technology. We are delighted to anounce the next IWCGT to take place in Berlin-Adlershof, Germany, in June 2026, hosted by IKZ. Please visit this homepage for further updates as they appear.
Welcome Message - About IWCGT-9
The workshop - the ninth of its series initiated by Hans Scheel and Tsuguo Fukuda - is devoted to Crystal Growth Technology, which also covers industrial scale technologies and equipment. The focus lies on the preparation of bulk and substrate crystals. The workshop aimed to provide links between R & D and actual production, besides bridging science and practice. International experts will present topical lectures with additional time allotted for discussions and debate. Attendees present their research at the evening poster sessions.
Topics of the workshop include for example:
- Growth technology for crystals for electronics and photovoltaics (Si, Ge, III-Vs, etc.)
- Substrate crystals for wide bandgap semiconductors (sapphire, SiC, GaN, AlN, Ga2O3, diamond, etc.)
- Growth of piezoelectrics, lasers, optical and luminescent materials, etc.
- Crystals for scintillators, detectors and large-scale facilities (halides, CdTe, KDP, etc.)
- Modeling, machine learning, AI and process control in crystal growth
- Tools and technologies for crystal growth (novel approaches, equipment, source and hot zone materials)
- Concepts and experience in crystal growth technologies going commercial
We are very pleased to invite you to this important workshop and experts gathering! Please save the date and share this information with interested colleagues.
