3-D projectors used without polarization goggles are the "Holy Grail" of optoelectronics. In the Institute's Laboratory of Semiconductor Characterization, we have developed two technologies which could pave the way to such projectors. Both are based on AlGaInN epitaxy on GaN substrates after lateral patterning. However, there are a lot of problems to be solved. The question is if they can be solved?

Join us on Wednesday, March 27, 2024 at 3:00 pm for the next online Unipress Thursday seminar. Prof. Mike Leszczyński from our Institute of High Pressure Physics PAS, the Laboratory of Semiconductor Characterization will give a talk entitled "Multicolour laser diode arrays for 3-D projectors - science fiction?".

Why nuclear energy is the optimal energy source and why it is so difficult to build nuclear power plant today? These and other fundamental questions will be addressed in the coming Unipress Thursday seminar by prof. Jacek Jagielski from the National Centre for Nuclear Research.

The seminar will be held on-line on Thursday, February 22, 2024 at 3:00 pm. The title of the presentation is "Energy for the future, or why we need nuclear power". Join the seminar if you would like to hear about the current concepts of Generation III and IV reactors, problems, risks and costs related to the implementation of nuclear power.

Implants allow us to recover quickly and efficiently after serious orthopedic injuries. It is known that the implant surface plays a key role in the organism's biological response, influencing implant regrowth and stability. In order to make implatnts more biocompatible, their surface can be covered by hydroxyapatite.

The next UNIPRESS Thursday seminar will be devoted to a novel method of implant coating - SonoNanoCoating (SNC). Urszula Szałaj from our Institute, the Laboratory of Nanomaterials will present its advantages and discuss the preliminary results obtained in her recent study. The title of her presentation is "SonoNanoCoating as a versatile method for hydroxyapatite coatings application on the surfaces of implants".

The seminar will be held on-line on Thursday, January 25, 2024 at 3:00 pm.To get the link to Zoom meeting, please contact us at dyrekcja@unipress.waw.pl

Ion implantation and annealing became recently an interesting route to change electrical properties of GaN, enabling for instance to go beyond the epitaxy capabilities in terms of doping. Understanding the process of defect formation seems to be crucial for the contol of the material properties after ion implantation.

Institute of High Pressure Physics invites to an open seminar of prof. Akira Uedono from the Faculty of Pure and Applied Sciences, University of Tsukuba, Japan. The title of his presentation is "Vacancy-type defects in GaN studied by positron anihilation spectroscopy".

The seminar will be held in person at Prymasa Tysiąclecia 98 (seminar room, second floor) in the Institute of High Pressure Physics on Friday, November 24, 2023 at 3:00 pm.
