IHPP PAS Seminar on Nitride Semiconductors
Dear Ladies and Gentlemen, We are pleased to invite you to the IHPP PAS Seminar on Nitride Semiconductors. The next presentation will be held in a hybrid mode – at the New Technologies seminar room, Al. Prymasa Tysiąclecia 98, and through Zoom platform (to get the link, please contact us at nitride_seminar@mail.unipress.waw.pl ). The next seminar is scheduled on Monday 28.08.2023 at 14:00. Speaker: Prof. Imad Belabbas (University of Bejaia, Laboratory of Physico-Chemistry of Materials and Catalysis) Title: Impact of dislocations on the thermal conductivity of gallium nitride: an atomistic investigation Abstract: (link) Sincerely, Tadeusz Suski
Institute Thursday Seminar
There is currently no viable solution for a robust bioresorbable orthopedic implant that can effectively address critical bone loss and bear mechanical loads. Therefore the development of new materials and technologies for biomedical applications is of vital importance. This issue will be discussed in the coming Thursday UNIPRESS seminar. Elżbieta Pietrzykowska from our Institute, Laboratory of Nanomaterials will give a talk on „Preparation of bioresorbable nanohydroxyapatite composites for orthopedic applications”. The seminar will be held on-line on Thursday, August 24, 2023 at 15:00. To get the link to join the seminar, please contact us at dyrekcja@unipress.waw.pl

Institute Thursday Seminar
Nanoporous GaN has recently emerged as a potential alternative material for AlGaN in the cladding layers of nitride laser diodes (LDs) due to its high refractive index contrast to GaN, tunable with porosity. In the next Thursday UNIPRESS seminar, dr inż. Marta Sawicka from our Institute, MBE Laboratory, will present the electrically pumped LDs with porous claddings and compare device characteristics with standard solutions. She will also present a novel concept of in-plane refractive index engineering involving selective area doping and material removal in the proces of electrochemical etching, that is proposed to fabricate photonic elements embedded inside the nitride structures. The Seminar "Application of nanoporous GaN in nitride laser diodes” will be held on Thursday, July 27, 2023 at 15:00 on Zoom platform.
