Instytut Wysokich Ciśnień

The Institute of High Pressure Physics Polish Academy of Sciences (IHPP PAS) is currently the leaseholder  of the Ammono Company, which manufactures gallium nitride (GaN) wafers with the ammonothermal method. The lease has been conducted in the best interest of nitride semiconductor science and technology.

The Ammono Company has been in receivership since 2015. The tenancy, founded by the Polish Ministry of Science and Higher Education, will enable a close cooperation between the groups involved in ammonothermal and Hydride Vapor Phase Epitaxy (HVPE) crystallization of GaN. The latter is performed at IHPP PAS and as a result of common projects a possible synergy of these two methods has been revealed. Ammono owns a pilot line of ammonothermal GaN wafers and IHPP PAS is building a pilot line for HVPE GaN substrates.

The lease and collaboration will lead to further development of both methods and, in the future, to merging of the two technologies and mass production of high-quality GaN wafers required for electronic and optoelectronic devices based on GaN. The tenancy will also enable knowledge transfer among researchers involved in GaN crystallization for more than two decades.

7th International Workshop on Crystal Growth Technology (IWCGT-7) will be held from 2nd to 6th July 2017 in Potsdam (near Berlin), Germany. Our Institute will be represented by Michal Fijalkowski and Michal Bockowski.

Two posters and one invited lecture will be demonstrated. The title of the lecture is Status, perspectives and trends on bulk growth of GaN. The posters are entitled: Highly resistive HVPE-GaN grown on native seeds with solid iron or methane as a source of dopants and Comparison of structural, optical, and electrical properties of highly conductive HVPE-GaN doped with Si or Ge and grown on native seeds, respectively.

The International Conference on Electron Microscopy is organized every three years by Polish Society of Microscopy. This year the confernce, 16-th in the series will be held in Jachranka near Warsaw from September 10 to 13, 2017.

The organizers announced the competition for the best
abstracts of PhD students, which was won by our colleague Joanna Moneta.

She will present her work devoted to studies of the relaxation processes of InGaN epitaxial layers during the Young Scientist Session.

Congratulations!
