Institute of High Pressure Physics

National Center for Research and Development (NCBiR), Poland and the National Science and Technology Council (NSTC), Taiwan are organizing a Taiwanese-Polish Symposium on Semiconductor Technology. The seminar will be held on November 6, 2023 at the National Applied Research Laboratories (NARLabs) in Hsinchu, Taiwan.

Prof. Izabella Grzegory has been invited to be the Polish coordinator of the 10th Polish-Taiwanese symposium. The substantive coordinators on the Taiwanese side are Dr. Mei-Yu Chang, Director of NARLabs International Affairs Office, and Dr. Chang-Hong Shen, Deputy Director of TSRI (Taiwan Semiconductor Research Institute).

Poland will be represented by six scientists from the University of Warsaw, the Warsaw University of Technology, the Wrocław University of Science and Technology, the Military University of Technology, the Institute of Microelectronics and Photonics - Łukasiewicz Network and IWC PAN. Lecture from IWC PAN entitled Physics and Engineering of GaN in UNIPRESS: crystals, quantum structures and devices will be delivered by Prof. Izabella Grzegory.

Detailed Symposium program is available here.

High pressure is known to be beneficial for enhancing the physical and magnetic properties of materials as well as improving the quality of synthesized material. The high pressure - high temperature synthesis (HP-HTS) technique developed at UNIPRESS provides a possibility to grow various kinds of materials in relatively large volumes (10-15 cm). The working principle of HP-HTS technique has been described in the recent article published by “Mohammad Azam, Manasa Manasa, Andrzej Morawski, Tomasz Cetner, and Shiv J. Singh” entitled “High Gas Pressure and High-Temperature Synthesis (HP-HTS) Technique and Its Impact on Iron-Based Superconductors” Crystals 13, 1525 (2023), Impact factor 2.7. The research team of Dr. Singh from NL-6 has studied the impact of high pressure on improvement of the superconducting properties and material quality of iron-based superconductors.

The second recenlty published paper presents a comparative study of the superconducting properties of iron-based high T_c materials by conventional synthesis process (CSP) and HP-HTS technique.

Laboratory NL 10, with the consent of the Director of the IWC PAN, announces a competition for the position of PostDoc as part of the NCN OPUS 45 project ref. 2022/45/B/ST5/04005 : Pressurized Glassy Materials for Innovative Energy Storage and Conversion.

The project links the physics of glasses and amorphous materials with materials engineering. It is the result of the discovery, made with the significant participation of IHPP PAS, that below the glass temperature Tg under high pressure there is a 'magic region' with a width of 50 - 100 K where compressimg can cause the appearance of even exotic physical properties, and they are retained after decompressing down to normal conditions. Obviously, this unusual property raises many 'fundamental' questions and is an opportunity for innovative applications. In this project, we focus especially on batteries for storing electric energy with glass electrodes. As we showed in our preliminary work in 2019, a properly 'designed' path of temperature and pressure changes can create nanocrystallites in the glass matrix, which are a source of high electrical conductivity, The mentioned 'annennaling' increases it further by 2 decades. It yields an excellent material for 'glass' battery electrodes, the surface of which practically does not change during the time of usage. This is a chance for 'eternal batteries', Nite that that just  relatively fast detoriation of  of storing ability during charging and discharging cycles is a great problem of existing solutions.

The candidate will work in the Innovation Park in Celestynów for a period of 12 - 24 months. The application deadline is 31.11.2023. Detailed competition conditions, including the candidate's expectations and qualifications, are provided in the attached document.

The project is implemented by the consortium of IHPP PAS (Lab NL10) and the Warsaw University of Technology, Faculty. Physics).
