Institute of High Pressure Physics

IHPP PAS was awarded by the Office of Naval Research Global with a second grant (N62909-21-1-2063). A three-year project titled ‘GaN substrates of the highest structural quality for high-power electronics’ started in September 2021.

This project is performed by the team working in the Crystal Growth Laboratory at IHPP PAS and is led by the head of the laboratory: Prof. Michal Bockowski. The work will be performed in close cooperation with our colleagues at Naval Research Laboratory in US.

The main objectives of this project is to develop the ammonothermal technology in order to obtain the highest structural quality 2-inch gallium nitride (GaN) substrates and to improve the crystallization from gas phase to deposit homo-epitaxial layers of the highest purity on the mentioned substrates.

The best technology for growing bulk GaN, in terms of structural quality, is ammonothermal. N-type Am-GaN substrates can be applied for building electronic Field Effect Transistors (FETs). This kind of devices require a GaN layer of the highest structural quality and purity. Gallium nitride of the highest purity can only be achieved by halide vapor phase epitaxy (HVPE). Therefore, a combination of the HVPE technology with Am-GaN substrates is the best path to achieve GaN-on-GaN structures of the highest crystallographic quality and the lowest donors and acceptors concentrations in the epitaxial layers.

Z przyjemnością informujemy, że Projekt LIDER "Podstawy technologii epitaksjalnych struktur (AlGaIn)N na kształtowanych przestrzennie podłożach GaN do produkcji matryc laserowych emitujących światło w zakresie 520-540 nm do celów trójwymiarowej projekcji obrazów" Ewy Grzanki, został zaakceptowany przez NCBiR.

The PASIFIC Fellowship Programme is a unique opportunity for researchers who want to undertake state-of-the-art research in a dynamic scientific environment. It will enable scholars of all nationalities and across all scientific disciplines to establish their scientific independence and conduct ground-breaking research.

For 2 years, the fellows will be hosted at one of the institutes within the Polish Academy of Sciences (PAS), which is one of the most prestigious research institutions in Poland. They will have the freedom to choose their research area, research supervisor, host institute as well as secondment organisations best suited for their research and career development.

The PASIFIC Fellows will be offered a monthly allowance of approx. €2,500 net. Those, who decide to come to Poland together with their families, may be entitled to an additional family allowance. In addition, they will be granted a research budget of up to €93,000 per project.

50 outstanding scientists will be selected in the two calls announced in 2021:

• The first call, in which 35 PASIFIC fellows will be recruited, will be open from March 15^th, 2021 to June 30^th, 2021. Selected researchers will be informed about evaluation results after approx. six months. They will be expected to come to Poland between January 2022 and March 2022.
• The second call, in which 15 PASIFIC fellows will be recruited, will be open from September 15^th, 2021 to December 30^th, 2021. Selected researchers will be informed about evaluation results after approx. six months. They will be expected to come to Poland between July 2022 and October 2022.
