This issue of Acta Physica Polonica A includes some of the presentations given at the 50th International School & Conference on the Physics of Semiconductors “Jaszowiec 2022”. The program of this jubilee event was special. In addition to regular sessions, it included a reminiscence session on the most  important achievements in the field of semiconductor physics over past years in the institutions organizing the Conference, which are:

• Institute of Physics of the Polish Academy of Sciences,
• Faculty of Physics (Institute of Experimental Physics and Institute of Theoretical Physics), University of Warsaw,
• Faculty of Fundamental Problems of Technology, Wrocław University of Science and Technology,
• Institute of High Pressure Physics of the Polish Academy of Sciences,
• Łukasiewicz Research Network — Institute of Microelectronics and Photonics.

The program also included a session devoted to the history of two companies that developed key semiconductor technologies in Poland, i.e., VIGO Photonics and AMMONO. As every year, outstanding world experts in the broad field of semiconductor physics, working both in foreign research centers (51 participants from 19 countries) and in Poland (211 participants from 11 scientific institutions and 8 companies), took part in “Jaszowiec 2022”. The topics of the Conference focused mainly on semiconductor nanostructures, two-dimensional (2D) materials, topological states of matter, spintronics, nanophotonics, quantum computing and quantum information processing, synthesis and characterization of semiconductor materials and electron devices. The Tutorial Session (School), addressed mainly to MSc students, PhD students, and young scientists, traditionally preceded the Conference, and this year it covered the subjects of 2D materials, quantum bits, non-linear spectroscopy, and photovoltaics.

We would like to express our gratitude to the members of the Program and the Advisory Committees for their wonderful work and contribution to the success of the jubilee “Jaszowiec 2022”. The most heartfelt thanks go to Anna Reszka and the Organizing Committee led by her, who made “Jaszowiec 2022” run smoothly and retain its magical atmosphere of a friendly scientific meeting. We also address special acknowledgments to Tomasz Jakubczyk, chairman of the Tutorial Session.  Finally, we would like to thank all the sponsors of the Conference: the Ministry of Education and Science, the Polish Academy of Science, the U.S. Army Combat Capabilities Development Command, and institutions organizing “Jaszowiec”, as well as commercial sponsors: COMEF, Technolutions, EDVAC, LABIS, Dr. Eberl MBE-Komponenten GmbH, and nextnano GmbH, for their financial and material support.
