3D – Photonic Heterostructures for High Temperature Applications
Aerospace applications, operating in extreme high temperature environments, require special heat treating mechanisms to guarantee their stable, long term operation. The aim of this project is to design, fabricate and characterize photonic structures that could be incorporated in such a system.
Aerospace applications operate in extreme high temperature environments and thus require special heat treating mechanisms in order to guarantee their stable, long term operation. Radiative cooling is considered to be an efficient mechanism of dealing with extreme heat influxes but its implementation is not a trivial task. In our project, we explore the enhancement of radiative cooling thermal protection systems (TPS) by introducing photonic heterostructures.
Our proposed system aims to improve the operational stability of aerospace applications by reflecting the incoming heat flux in a controlled and systematic way. This approach aims to advance next generation aerospace systems that are expected to perform in even more adverse temperatures and extend further their service lifetime.

The goal of the project is to design, fabricate and characterize 3D photonic heterostructures for stable operation in a high temperature environment.
In particular, we are interested in the theoretical modeling and characterization of high temperature, stable and broadband photonic reflectors that will be proposed for radiative cooling applications in the aerospace industry.
The thesis will give you the opportunity to work with modern simulation software, acquire lab experience and the chance to work in the state-of-the-art fabrication lab of Binnig and Rohrer Nanotechnology Center (BRNC).
