Introduction to the Action

The COST Action “European Network for Innovative and Advanced Epitaxy”, named OPERA, will build a new and innovative European Network composed of expert communities in epitaxial growth focusing on different materials classes: conventional semiconductors, oxides and 2D materials.

It aims to bridge the gap between traditionally separated scientific communities, both academic and industrial, having the common goal to combine complementary knowledge, push further the material maturation, and exploit epitaxial combinations of the different material classes in order to unveil new properties and produce new functionalities.

Based on this organization, the OPERA COST Action will foster interdisciplinary collaborative research activities allowing maintaining European epitaxy at the topmost worldwide level of research and innovation.

Meet our
Working Groups

WG1

Fundamental research – New Materials

In material science, the ambition is to address new challenges, pushing the frontiers of knowledge. To address Sustainable Development Goals: the fundamental key in the epitaxy field must be addressed for mastering “actual” materials and developing new materials.

WG2

Applications-oriented material developments

Optimization of materials for innovative devices: Novel device performances rely on material properties. In this regard, materials must be developed considering device requirements.

WG3

Industry-oriented materials development and technological transfers

To develop technological transfer-ready devices, the fundamental challenges of tasks 1 & 2 must be addressed by taking into account market–proof device specifications.
