Detachable Epitaxial Films For Applications in Solar Energy
We have recently discovered the ability to grow high quality epitaxial semiconducting films on sapphire and then transfer them to convenient carriers for subsequent applications. In essence, it appears as if transient covalent bonds are developed locking the initial ad-atoms into the symmetry of the lattice which are subsequently broken. This allows us to readily remove large sections of undisturbed film, transfer to a range of alternate substrates and reuse the sapphire substrates an arbitrary number of times without polishing or extensive surface treatment. The films can be very high quality, suitable for a wide range of detector & sensor applications, solar cells and flexible electronics.

Welcome
to the European Conference on Materials and Technologies for Sustainable Growth website.
ECo MaTech will be held in Bled (Slovenia) from 19th to 21st of September 2013.
Eco MaTech is the third edition of a conference that started in 2009. The aim of ECo MaTech is to gather representatives of academic and R&D institutions, industry, governmental agencies and civil society to:
- present their work, ideas and products,
- increase fruitful exhanges between all the actors involved in sustainable growth technologies,
