Institute of High Pressure Physics

Material doping without impurity atoms is possible in nitrides due to the presence of polarization gradient in the crystal. The emergence of polarization charges in concentration-graded AlGaN and InGaN materials will be discussed during the next Unipress Thursday Seminar by dr Konrad Sakowski from Laboratory of Nitride Semiconductor Physics, Institute of High Pressure Physics in the talk „Polarization doping in AlGaN and InGaN — numerical simulations”. Additionally, the issue of mobile charges in polarization doped alloys and the potential application of polarization doping for UV heterostructures will be discussed.

Join us online via Zoom platform on Thursday, November 28, 2024 at 3:00 pm. To get the link to Zoom meeting, please contact us at dyrekcja@unipress.waw.pl
