8th International Workshop on Crystal Growth Technology (IWCGT-8)
Berlin/Germany   ·   May 29 – June 2, 2022

Crystal growth will remain utmost important, continuing to shape the foundation of major advances in technology. We are confident that face-to-face workshops with a lot of space for personal interaction and individual meetings "off the record" will remain essential for our scientific business. With strong support from the community, we will thus run this conference in a face-to-face format. We have secured funding, the hotel, a local team and invited speakers to make this event as successful as the previous ones.

We are delighted to all of you that attend and are part of the crystal growth community in these troublesome times!

Welcome Message - About IWCGT-8

The workshop - the eighth of its series initiated by Hans Scheel in 1998 - 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 IWCGT-8, originally scheduled for June 2020, had to be postponed to 2022 due to the worldwide COVID pandemic.

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:

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.

Workshop Details

Conference Time

The conference begins on Sunday, May 29 with a welcome reception starting around 4 pm and ends on Thursday, June 2 after lunch at about 2 pm; see the workshop schedule.

Conference Venue

The Conference is held at the Pentahotel Berlin-Köpenick, Grünauer Str. 1, 12557 Berlin. The venue can be easily accessed from the city or the airport by public transport using the local trains (S-Bahn) to stations "Köpenick" or "Adlershof" and then with the tramway (lines 61, 63 or 68) to station "Köllnischer Platz".

Scope of the Workshop

Crystal growth has contributed to and enabled a substantial part of modern technology development, from piezoelectric, optical, and laser applications to today’s overwhelming photovoltaic market and booming use of electronic devices in information technology, communication, system control and power conversion. Producing crystals of higher perfection and at a lower cost is a prerequisite for their applications in any new functionalities, and efficient devices are the drivers of a rapidly changing world. Crystal growth technologists address these demanding requirements, and this workshop is where they meet.

Since its initiation in 1998 by Hans Scheel, the workshop is being perceived as a meeting of experts in crystal growth technology, in which invited renowned speakers give an in-depth presentations about a particular problem or challenge in the application-oriented crystal growth, and with lots of space for discussions and networking opportunities.

This approach has been proven very successful over these years and is continued at IWCGT-8 as well. The retreat-type of scenery and surroundings of the venue, long enough coffee breaks for refreshing and the relaxed barbecue dinner, not to forget, the two evening poster sessions are means to stimulate deeper discussions and to set the stage for a lively networking atmosphere among the participants. All attendees and in particular, young researchers, are asked to prepare abstracts and to present their own work as posters - although this is of course not mandatory, you might as well attend without an own presentation.

Sponsoring and Exhibition

We will feature an industrial exhibition during the workshop. We can also provide means to display your services and products, and we have opportunities for sponsoring that will highlight your support of the community. If you are interested to present your company or institute, meet the attendees and/or support us, please contact Radhakrishnan Sumathi. We have the right bundle for your successful participation!

Lecturers a.k.a. Invited Speakers (alphabetical order)
Poster Presentations (alphabetical order)

Info for invited lecturers: We all equipment (laptop with Adobe Acrobar reader and Office 2019, beamer, laser pointer etc.) available. Of course you can also use your own laptop, but please provide adaptors for HDMI output.

Info for poster presenters: We have portrait poster walls that have a fixation area (inner border) of 145 cm vertical and 115 cm horizontal. We typically use DIN A0 posters (119 cm * 84 cm), but that's just a suggestion.

How to Register and Accommodate

The workshop registration is a four-step process; each step can be conducted separately:

  1. Pre-registration to submit your personal data (without any obligation)
  2. Abstract submission/upload
  3. Final registration to confirm your attendance
  4. Payment of the attendance fee (see below)

Click here to   Login for IWCGT-8   (participants only).

The IWCGT-8 registration is handled by ConfTool Pro, a software to handle all registration, abstract submission, and payment matters. All data is handled securely and according to EU regulations.

Invitation letters are available for download after pre-registration on the registration site. Visa invitation letters and invoices are issued for download after final registration. An immediate receipt will be issued after payment is completed.

How to Submit an Abstract

Abstract submission deadline had been prolonged to 31 March 2022 (as the final deadline) and is now closed except for the invited speakers. As the lectures are by invitation only, regular participants will present posters, subject to abstract submission and acceptance by the conference organizing committee.

The abstract size is one A4-page in PDF format. Please take care to save your document in PDF/A format so that all fonts are embedded; e.g. in Word, export (rather than print) to PDF and in the options dialog available during saving, check the "PDF/A compatible" option.

The author should include figures, tables, and references within the one page limit. The title should be placed at the top of the abstract, followed by the authors' names, affiliations, and e-mail address of the presenting author, a blank line, and the main text (optionally with figures). Acknowledgements and references might be added at the end of the abstract.

The abstract should have the following format:

A book of abstracts will be provided at the workshop for all participants.
