Institute of High Pressure Physics

Would you like to know why the conductivity in AlN, AlGaN and GaN sometimes remains limited despite intentional doping? And how to find the cause of electrical compensation distinguishing between acceptor impurities, native vacancies, and amphoteric donors?

During the next Unipress Thursday Seminar, Dr. Igor Prozheev from the University of Helsinki, Finland will present advanced experimental and theoretical methods, such as ion implantation and positron annihilation combined with DFT calculations, to reveal how these point defects impact the performance of opto- and power electronic devices. The talk tile is „The Alchemy of Nitrides: from Experiment to Theory”.

Join us live in the Institute of High Pressure Physics, al. Prymasa Tysiąclecia 98, Warsaw, seminar room on II floor, or online via Zoom platform on Thursday, Spetember 25, 2025 at 3:00 pm. To get the link to Zoom meeting, please contact us at dyrekcja@unipress.waw.pl
