The papers included in this volume of Acta Physica Polonica A are a contribution to the XIII International Conference on Ion Implantation and Other Applications of Ions and Electrons ION 2022, which was held in Kazimierz Dolny, Poland, on June 27-30, 2022. The Conference was organized by Maria Curie-Skłodowska University in Lublin in cooperation with the Lublin University of Technology and the Polish Physical Society.

The Conference was attended by 44 participants from Belarus, Germany, Poland, South Africa, and Ukraine, who had the opportunity to meet in a friendly atmosphere in the beautiful historic town of  Kazimierz Dolny to exchange experience in the eld of ion implantation and the application of electron beams and plasma. The idea of the biennial ION Conferences was stimulated by the permanent interest in ion beam methods, which started from fundamental studies in ion and plasma physics and have established themselves as the standard techniques for material modication and characterization. A wide range of topics was addressed during the ION 2022 Conference, including inter alia: ion beam modication of semiconductors, metals, insulators, and polymers, microstructural investigations of ion-implanted and swift heavy ion-irradiated materials, tribological properties of metallic and ceramic plasma-deposited coatings, computer simulations of post-implantation damage and ionization processes in ion sources. The diversity of topics was a great advantage for the participants of the Conference because it oered new approaches to solving scientic and technological problems.

During the four days of plenary sessions, 14 invited talks and 2 special lectures were given, reviewing actual topics of interest to the participants. The ION 2022 Conference also featured 13 oral presentations and 27 poster contributions with detailed information. Nine persons participated in the Young Scientists Contest.

We would like to thank everyone who contributed to the organization of our Conference in the dicult year of 2022. Special thanks are due to Mr. Janusz Filiks, Dr. Andrzej Droździel, and Dr. Krzysztof Pyszniak for their work, as well as to Dr. Wolfgang Skorupa for giving us a traditional organ concert in the Fara church in Kazimierz Dolny.

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.
