The CVD lab includes:

1. Remote plasma MOCVD system (Spirit 92 reactor) designed for the growth and processing of III-V semiconductors (InP, GaN, InN,…);
2. CVD-sputtering assisted system (Goldage) for the growth of oxides, TCOs, ceramics, and metals;
3. PECVD system (Silvy reactor) for the growth of Si and SiGe based alloys. All our system have a plasma integrated source as well as in-situ real-time monitoring techniques of spectroscopic ellipsometry, mass spectrometry and optical emission spectroscopy for the kinetic analysis of growth and monitoring of processes and material quality.

Following that, the materials are characterized  and investigated  at the nanoscale, ultimately to be used for a variety of specific application spanning  from  photonics, photovoltaics and for sensors.
