4th international workshop Hexagonal SiGe
14-15 September 2026
University of Twente, Enschede, The Netherlands
The 4thInternational Workshop on Hexagonal SiGe and related materials will take place on 14-15 September 2026 at the Amphitheater of the University of Twente, Enschede, The Netherlands. The University of Twente is situated on a beautiful Campus full with greenery on the East Side of The Netherlands. The key objective of this interdisciplinary workshop was to identify challenges towards a fundamental understanding of the main properties of hexagonal silicon and related materials. This is the fourth edition of a series of workshops on the physics, chemistry and applications of group IV hexagonal materials after the three successful previous editions in Eindhoven (2023), Milan (2024) and Paris (2025). By bringing the most recent experimental and theoretical viewpoints together, the following topics were covered:
- Growth of Hex-SiGe nanowires.
- Planar growth of Hex-SiGe and integration on silicon.
- Characterization of structural, electronic, and optical properties of Hex-SiGe.
- Defects in Hex-SiGe.
- First principles calculations of Hex-SiGe electronic properties.
- Modeling of Hex-SiGe structural and functional properties.
- Pressure-induced phase transitions: towards Hex-SiGe.
- Towards Hex-SiGe-based devices.
- III-Vs, II-VIs and related materials.
Recent advances, such as the demonstration of direct bandgap emission in hexagonal SiGe nanowires and improved modeling of phase stability, have significantly expanded the frontiers of this emerging material system. The workshop provided a unique platform to exchange knowledge, discuss open challenges, and outline future directions for both fundamental research and technological applications.
